A Comprehensive Guide to Probiotic and Fermented Foods of Punjab

Punjab, the land of five rivers, is a state in northwestern India. It shares borders with Jammu and Kashmir to the north, Himachal Pradesh to the east, Haryana to the south and southeast, Rajasthan to the southwest, and the Pakistani province of Punjab to the west. The state lies in the fertile Indo Gangetic plain, primarily consisting of alluvial soil deposited by the rivers Sutlej, Beas, Ravi, and their tributaries. The climate is semi arid and continental (classification: BSh in the southwestern districts, Csa in the northeastern districts). The climate is characterized by extreme seasonal variations. Summers (April to June) are very hot, with temperatures ranging from 35 to 45 degrees Celsius, occasionally reaching 47 degrees Celsius in the southwestern districts (Fazilka, Sri Muktsar Sahib, Bathinda, Mansa). Winters (December to February) are cold, with temperatures dropping to 0 to 5 degrees Celsius, and occasional fog and frost in the northern districts (Amritsar, Gurdaspur, Pathankot, Tarn Taran). The monsoon season (July to September) brings moderate rainfall (400 to 800 millimeters across the state, higher in the northeast, lower in the southwest). Humidity is moderate to high during the monsoon but low for the rest of the year.

This climate has profoundly shaped Punjab's fermentation traditions. The extreme summer heat accelerates fermentation but also increases the risk of spoilage. The cold winter temperatures slow fermentation significantly, requiring the use of warm spots (near the hearth, inside quilts, in the oven with the pilot light). The state is also one of India's largest milk producers (the "white revolution" started in Punjab and Haryana), and fermented dairy products are absolutely central to daily life. Punjab is famous worldwide for its lassi, dahi, makhan, and paneer (though paneer is not fermented). The state is home to the Punjabi people, with a culinary heritage shaped by the Jat, Rajput, Brahmin, Khatri, Arora, Saini, Ahir (Yadav), Gujjar, and Ramgarhia communities, as well as the significant Sikh population. The cuisine is predominantly vegetarian in many communities, but dairy and fermented dairy feature exceptionally heavily, even more so than in Haryana. Meat is also consumed by many communities, but fermented meat products are not traditional in Punjab (unlike in the Himalayan regions). Fermented foods are intrinsic to the traditional Punjabi diet. The state is particularly known for its fermented dairy products (dahi, lassi, chaas, makhan, ghee from cultured butter, kadhi) and its unique fermented flatbreads (particularly those made from pearl millet (bajra) and corn (makki) during the winter). Unlike the rice based ferments of South India, Punjab's ferments are based on wheat, corn, pearl millet, gram flour (besan), and dairy.

Scientific studies have isolated several probiotic lactic acid bacteria from Punjab's fermented foods, including various species of Lactobacillus, Lactococcus, Leuconostoc, Pediococcus, and Enterococcus. The state's fermented milk products, particularly dahi and lassi, are well studied for their probiotic potential. The traditional Punjabi diet, rich in fermented dairy, is one of the reasons for the robust gut health and overall health of the rural Punjabi population, despite high caloric intake.

This document organizes the major fermented foods of Punjab by substrate type: fermented flatbreads and grain products, fermented dairy products (the most diverse and essential, even more so than Haryana), fermented lentil and pulse products, fermented pickles and condiments, fermented beverages, and other miscellaneous ferments.

Part 1: Fermented Flatbreads and Grain Products

Punjab is a major producer of wheat, corn (makki), and pearl millet (bajra). Fermented flatbreads are a staple of the rural diet, particularly during the winter months when corn and bajra are in season. The practice of fermenting the dough improves digestibility, enhances mineral bioavailability (particularly iron and zinc in millets and corn), and creates a characteristic tangy flavor.

Bajre Ki Roti (Fermented pearl millet flatbread)

Bajre ki roti is a staple flatbread in rural Punjab, particularly in the southwestern districts (Bathinda, Mansa, Fazilka, Sri Muktsar Sahib, Faridkot) where pearl millet is widely cultivated. The traditional version uses fermented dough. Pearl millet flour (bajra) is mixed with warm water, salt, and a small amount of sour buttermilk (chaas) or yogurt (dahi) as a starter. The dough is left to ferment for 6 to 8 hours (or overnight). In the extreme summer heat (40 to 45 degrees Celsius), fermentation completes in 4 to 5 hours. In winter (0 to 5 degrees Celsius), the dough is placed near the hearth (chulha) or wrapped in a quilt (rajai) and may take 12 to 16 hours. The fermentation is driven by LAB from the buttermilk, primarily Lactobacillus plantarum, Lactococcus lactis, and Leuconostoc species. Fermentation reduces the phytic acid content of bajra (which is very high), significantly improving the bioavailability of iron and zinc. It also breaks down complex proteins, making the roti softer, less gritty, and more digestible. After fermentation, the dough is rolled into flatbreads and cooked on a hot griddle (tawa) over an open flame, then often finished directly over the flame to puff up (this step is called "dhakna"). The cooking kills all live microbes. Fermented bajre ki roti is typically served with ghee (clarified butter), white butter (makhan), sarson ka saag (mustard greens curry), garlic chutney (lehsoon di chutney), pickles, and a generous glass of lassi or chaas. It is considered a winter staple, eaten daily from November to February.

Makki Di Roti (Fermented corn flatbread)

Makki di roti is arguably the most iconic flatbread of Punjab, traditionally eaten with sarson da saag (mustard greens curry). The dough is made from corn flour (makki ka atta), which is coarser than wheat flour and does not contain gluten. This makes the dough inherently brittle and difficult to roll. Fermentation improves the texture significantly. Corn flour is mixed with warm water, salt, and a small amount of sour buttermilk (chaas) or yogurt. The dough is left to ferment for 4 to 6 hours. The fermentation is driven by LAB, primarily Lactobacillus plantarum and Leuconostoc species. Fermentation partially breaks down the starches and proteins, making the dough more pliable and less prone to cracking. It also reduces the phytic acid in corn (corn phytic acid binds iron and zinc) and enhances the bioavailability of niacin (vitamin B3, which is bound in corn as niacytin and is not bioavailable without alkali or fermentation treatment). After fermentation, the dough is patted by hand into flatbreads (rolling is difficult) and cooked on a hot griddle (tawa). The cooking kills all live microbes. Makki di roti is served with sarson da saag, white butter (makhan), and jaggery (gur). It is a winter staple, consumed daily from December to February.

Fermented Wheat Roti (Khatti Roti)

In traditional Punjabi households, whole wheat roti is also made from fermented dough, particularly during the winter months when a sour, tangy flavor is desired. The dough is prepared with whole wheat flour (gehu ka atta), water, salt, and sour buttermilk or yogurt, and fermented for 4 to 6 hours. Fermented wheat roti (called "khatti roti," meaning sour roti) has a tangy flavor, a softer texture, and is more digestible than unfermented roti. It also stays soft for longer, making it ideal for packing in lunchboxes (tiffin). The cooking kills live microbes. This practice is common in rural areas.

Fermented Missi Roti (Spiced fermented gram flour flatbread)

Missi roti is a popular flatbread made from a mixture of whole wheat flour and chickpea flour (besan), spiced with green chilies, ginger, onions, fenugreek leaves (kasuri methi), and coriander. A fermented version is common in Punjab, where the dough is made with sour buttermilk (chaas) instead of water and left to ferment for 4 to 6 hours. The fermentation makes the missi roti softer and adds a tangy flavor that complements the spices. It is typically served with white butter (makhan), yogurt (dahi), and pickles. The cooking kills live microbes.

Fermented Thepla (Spiced fermented flatbread, Gujarati origin but adopted)

Thepla, originally a Gujarati flatbread, has been adopted in Punjab, particularly in urban areas. A fermented version is made by preparing the dough with sour yogurt (dahi) instead of fresh curd, and leaving it to ferment for 2 to 4 hours. The fermentation adds a tangy flavor and improves shelf life (theplas made from fermented dough stay soft for days). The cooking kills live microbes.

Raab / Rabri (Fermented pearl millet porridge)

Raab (also called "rabri" in Punjab, not to be confused with the sweet dessert) is a traditional fermented porridge made from pearl millet flour (bajra). Bajra flour is mixed with water, salt, and sour buttermilk (chaas), and left to ferment for 6 to 8 hours. After fermentation, the mixture is cooked into a thick, sour, savory porridge. Raab is a staple food in rural Punjab, particularly during the winter months. It is consumed as a breakfast or as a meal replacement for agricultural laborers. Raab provides sustained energy, warmth (it is served hot), and enhanced nutrition. The cooking kills live microbes, so it is not probiotic, but the nutritional benefits of fermentation remain. In some households, raab is consumed raw (uncooked) after fermentation; this version is a genuine probiotic food but carries a higher risk of contamination. Pregnant women and immunocompromised individuals should consume only the cooked version. Raab is often eaten with chopped onions, green chilies, and a dollop of ghee.

Fermented Kanji (Bajre ka kanji or fermented millet beverage)

A thin, fermented beverage called "kanji" is made from pearl millet flour (bajra). Bajra flour is mixed with water, salt, and a small amount of sour buttermilk, and left to ferment for 6 to 8 hours. The resulting thin, sour, effervescent liquid is consumed as a beverage. It is similar to the fermented millet kanji of Rajasthan and Haryana. This is a genuine probiotic beverage if consumed raw (uncooked), and it is typically consumed raw. It should be consumed within 24 hours. This product is rare and is confined to very traditional rural households.

Part 2: Fermented Dairy Products

Punjab has an exceptionally strong dairy tradition, arguably the strongest in India. The state is a major milk producer, with indigenous cattle breeds (Sahiwal, Rathi, Tharparkar) and water buffalo (Murrah breed). The "white revolution" (Operation Flood) was centered in Punjab and Gujarat. Fermented dairy is consumed multiple times daily in every household. Unlike South India, where curd is often a final course, in Punjab fermented dairy is central to the entire meal and is often the main event. The famous Punjabi "lassi" is world renowned.

Dahi (Curd or Yogurt)

Dahi is prepared by boiling fresh cow or water buffalo milk, cooling to lukewarm (40 to 45 degrees Celsius), and inoculating with a starter culture from a previous batch of dahi (back slopping). The fermentation is driven by Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus, along with mesophilic Lactococcus lactis and Leuconostoc species in traditional preparations. In the extreme summer heat (40 to 45 degrees Celsius), dahi sets in 3 to 4 hours. In winter (0 to 5 degrees Celsius), the inoculated milk is placed in a warm spot (near the hearth, inside a quilt wrapped pot, inside the oven with the pilot light) and may take 12 to 16 hours to set. Traditional households use earthen pots (matka) for setting dahi. The porous clay allows evaporative cooling in summer (preventing over souring) and retains heat in winter (when the pot is wrapped). Dahi is consumed daily: plain, mixed with rice (dahi chawal), used to make lassi, chaas, kadhi, and raita, or eaten with roti (dahi roti). Dahi is a genuine probiotic food. The Punjabi dahi is typically thick, creamy, and mildly sour, with a characteristic "jelly like" consistency when set properly.

Lassi (Sweet or salted fermented buttermilk drink)

Lassi is arguably the most famous fermented beverage of Punjab, recognized worldwide. It is a thick, rich, creamy fermented buttermilk drink. Lassi is made by churning fresh dahi with a small amount of water (less water than chaas, resulting in a thick consistency) and then adding sugar (sweet lassi) or salt (salted lassi). Sweet lassi is often flavored with cardamom powder (elaichi), rose water (gulab jal), or saffron (kesar). Salted lassi is flavored with roasted cumin powder (jeera) and black salt (kala namak). Lassi is consumed as a beverage with meals, as a mid morning refreshment, as a post meal digestive, or simply as a refreshing drink on a hot summer day. It is also served as a welcome drink to guests. Lassi contains live LAB and is a genuine probiotic beverage. In Punjab, lassi is often served in large metal glasses (pint or quart sized) or even in earthen cups (kulhad). It is thick enough to be eaten with a spoon. The butter (makhan) that separates during churning is skimmed off and eaten separately. Lassi is so central to Punjabi culture that the phrase "Punjab di lassi" is a cultural icon.

Chaas (Spiced thin buttermilk)

Chaas (also called "chhachh" in Punjabi) is a thinner, more watery version of buttermilk than lassi. It is made by churning fresh dahi, diluting with a larger amount of water (typically 1:3 or 1:4 ratio of curd to water), and seasoning with salt, roasted cumin powder, black salt, asafoetida (hing), and sometimes finely chopped green chilies, ginger, and coriander leaves. Chaas is consumed as a hydrating beverage, especially during the hot summer months. It is lighter and less rich than lassi, and is often drunk with lunch and dinner. Chaas contains live LAB and is a probiotic beverage. Punjabi chaas is typically saltier and more cumin flavored than the chaas of other states.

Makhan (Fermented cultured butter)

Makhan (white butter) is the butter that separates from dahi during churning. Fresh dahi is churned (traditionally in a wooden churn called "bilona" or "madhanu"), the butter rises to the top, and is skimmed off. This butter is called "makhan" and is not heated. It retains live LAB from the dahi, making it a genuine probiotic food (unlike ghee, which is heated). Makhan is soft, white, and spreadable. It is consumed daily: spread on roti (especially makki di roti and bajre ki roti), mixed into khichdi, added to dal, or eaten plain with a sprinkle of salt and black pepper. Makhan is rich in probiotics and fat. It is a prized food in rural Punjab. The buttermilk left behind after removing the butter is used to make lassi or chaas.

Ghee (Clarified butter from cultured butter)

Traditional Punjabi ghee is made from makhan (cultured butter), not from fresh cream. The makhan is heated gently until the water evaporates and the milk solids separate, leaving pure, golden clarified butter (ghee). The culturing of the dahi and the use of makhan give the ghee a distinct, nutty, complex flavor that is far superior to ghee made from fresh cream. The heating kills all live microbes, so ghee is not probiotic, but it is nutritionally superior (contains more short chain fatty acids, butyrate, and fat soluble vitamins) and has a very long shelf life. Ghee is used as a cooking medium (for frying, tempering), as a condiment (drizzled over roti, dal, rice, or paratha), and in traditional medicine (Ayurveda) and Sikh religious rituals (karah prasad). Punjabi "desi ghee" is famous across India.

Kadhi (Fermented yogurt curry)

Kadhi is a staple of the Punjabi thali, consumed almost daily in many households, particularly during the summer months. Sour dahi (dahi that has fermented for 2 to 3 days, becoming more acidic) is whisked with chickpea flour (besan), water, ginger paste, green chilies, turmeric, and asafoetida. The mixture is heated gently (stirring continuously to prevent curdling) until it thickens. A tempering (tadka) of mustard seeds, cumin seeds, fenugreek seeds (methi), dried red chilies, and a generous amount of ghee is added. Punjabi kadhi is thick, sour, and spicy. It is not sweet (unlike the Gujarati version). It is traditionally served with rice (kadhi chawal) or with khichdi. The heating step kills most live microbes if the kadhi is boiled. Traditional preparation involves gentle simmering (not boiling), preserving a portion of the probiotics. Kadhi is considered a digestive aid and is often served after a heavy meal. A very popular variation includes pakode (chickpea flour fritters) added to the kadhi. The pakode are made from besan batter (sometimes fermented with buttermilk for 1 to 2 hours), deep fried, and then added. This dish is called "kadhi pakora."

Raita (Yogurt based side dish)

Raita is a side dish made from fresh dahi (yogurt) mixed with grated or chopped vegetables (cucumber, carrot, beetroot, onion, tomato, boiled potato), spices (roasted cumin powder, black salt, chili powder), and sometimes fruits (pineapple, pomegranate, apple, banana) or herbs (mint, coriander). Raita is not fermented separately (the dahi is already fermented), but it is a live, probiotic dish because the dahi is not heated. Raita is served as a cooling accompaniment to spicy biryanis, pulaos, kebabs, and curries. The most common raita in Punjab is "boondi raita" (made with boondi, small fried chickpea flour balls) and "cucumber raita" (kheere ka raita).

Punjabi Rabri (Fermented clotted sweet cream, different from the porridge)

Punjabi rabri (or rabdi) is a sweet, clotted cream dessert made by boiling full fat milk for hours, reducing it, and adding sugar, cardamom, and nuts. This is not fermented. However, in rural Punjab, a fermented version of rabri similar to the Rajasthani fermented sour cream (described in the Rajasthan guide) exists. This product is called "khatta rabri" or "dahi rabri" and is consumed as a condiment with roti. It is extremely rare.

Chass (Another name for chaas)

Chass is simply another spelling for chaas, the spiced buttermilk beverage.

Part 3: Fermented Lentil and Pulse Products

Punjab has a tradition of fermenting lentils and pulses, similar to Haryana and other North Indian states. Sun dried fermented lentil wafers (papad, vadi, mangodi, bari) and fermented lentil dumplings (dahi bada, bhalla) are common.

Papad (Fermented lentil wafers)

Papad is a traditional fermented wafer made from lentil flour (urad dal, moong dal, chana dal, or a mixture). Punjab is a major producer of papad, particularly in the districts of Amritsar, Jalandhar, Ludhiana, and Patiala. The process: lentil flour is mixed with water, salt, and a small amount of baking soda or leftover fermented batter, formed into a stiff dough, and left to ferment for 4 to 6 hours. After fermentation, the dough is rolled into thin rounds and sun dried for 1 to 3 days. The sun drying allows for continued surface fermentation by halotolerant LAB. The dried papad is stored. Before eating, it is roasted over an open flame, deep fried, or microwaved. The high heat kills live microbes, but the fermentation enhances digestibility and reduces flatulence causing oligosaccharides. Papad is a staple accompaniment to meals. Punjabi papad is often spiced with black pepper (kali mirch papad) or cumin (jeera papad).

Vadi / Bari (Sun dried fermented lentil dumplings)

Vadi (also called "bari" or "badi") are sun dried dumplings made from fermented lentil paste. Urad dal or moong dal is soaked, ground into a paste with water, salt, and spices (ginger, green chilies, asafoetida, sometimes fennel seeds (saunf)), and left to ferment for 4 to 6 hours. The fermented paste is then shaped into small dumplings and sun dried for 2 to 3 days. The sun drying allows for surface fermentation. The dried vadi are stored and used as an ingredient in curries (vadi ki sabzi) or added to dal. The cooking kills live microbes. Vadi are particularly common in Punjabi cuisine, especially during the winter months.

Mangodi (Fermented sun dried lentil dumplings, similar to vadi)

Mangodi (also called "mangori" or "mongodi") is similar to vadi but is typically made from moong dal. Mangodi is used extensively in Punjabi cuisine, particularly in curries with spinach (palak mangodi) or potatoes (aloo mangodi).

Dahi Bada (Fermented lentil dumplings in yogurt)

Dahi bada (also called "dahi vada" or "dahi bhalla") is a very popular snack in Punjab, served at weddings, festivals, and as street food. Urad dal (black gram) is soaked for 4 to 6 hours, then ground into a smooth batter with water, salt, ginger, and green chilies. The batter is left to ferment for 4 to 6 hours. The fermentation is driven by spontaneous LAB (from the dal, the grinding stone, and the environment). After fermentation, the batter is shaped into small dumplings (bada) and deep fried until golden brown. The fried dumplings are then soaked in warm water (to remove excess oil) and then transferred to fresh, cold, whisked dahi (yogurt). The bada absorb the yogurt, becoming soft and tangy. The dish is served with sweet tamarind chutney (khatti meethi chutney), green chutney (coriander and mint), roasted cumin powder, black salt, and a sprinkle of chili powder and sev (crispy chickpea noodles). The fermentation of the batter makes the bada lighter, softer, and more digestible. The deep frying kills the LAB from the batter, but the final dish is served with live yogurt (dahi), making dahi bada a probiotic dish (from the yogurt, not from the fried bada). Dahi bada is often served chilled.

Bhalla (Fermented lentil dumplings, larger than bada)

Bhalla is similar to dahi bada but is larger and often made from a mixture of urad dal and moong dal. The preparation is identical. Bhalla is typically served with dahi and chutneys, often with the addition of boiled potatoes, chickpeas (chana), and sev on top, making it more substantial. This is sometimes called "dahi bhalla chaat."

Part 4: Fermented Pickles and Condiments

Punjab's pickling tradition is rich and diverse, similar to that of Haryana and Rajasthan. Pickles are typically made with mustard oil as the primary preservative, and they rely on salt and oil for preservation, with spontaneous LAB fermentation occurring over several weeks. Punjab is famous for its mixed vegetable pickles and "panchranga achar" (five color pickle).

Aam ka Achar (Fermented mango pickle)

Raw mango pieces are mixed with salt, chili powder, asafoetida (hing), fenugreek powder (methi), fennel powder (saunf), nigella seeds (kalonji), and mustard oil. The mixture is packed into a ceramic or glass jar and left to ferment in the sun for 15 to 20 days. The fermentation is driven by halotolerant LAB, primarily Lactobacillus plantarum and Tetragenococcus halophilus. Punjabi mango pickle often uses a higher proportion of fennel and nigella seeds. It is served as a condiment with roti, paratha, rice, and dal. Mango pickle is a staple in every Punjabi household.

Nimbu ka Achar (Fermented lime pickle)

Lime pickle is made by fermenting whole or quartered limes with salt, chili powder, asafoetida, and mustard oil. A small amount of jaggery or sugar is often added for a sweet sour flavor. Fermentation takes 15 to 30 days. The limes soften completely and turn a dull yellow brown. Nimbu ka achar is served with every meal.

Hari Mirch ka Achar (Fermented green chili pickle)

Green chilies are slit (or left whole) and packed with salt, mustard oil, asafoetida, and lemon juice. The pickle is left to ferment in the sun for 10 to 15 days. The chilies soften and become intensely salty and sour. This pickle is served as a condiment and is particularly popular in the winter months.

Gajar ka Achar (Fermented carrot pickle)

Carrot pickle is made from carrot pieces (often with the addition of green chilies, cauliflower (gobhi), turnips (shalgam), or radish (mooli)) mixed with salt, mustard oil, chili powder, asafoetida, and fenugreek powder. Fermentation takes 10 to 15 days. This pickle is very popular in the winter months (December to February) when these root vegetables are abundant. In Punjab, a winter pickle called "gobhi shalgam gajar ka achar" (cauliflower, turnip, carrot pickle) is famous.

Mixed Vegetable Achar (Panchranga Achar)

Panchranga achar (five color pickle) is a traditional Punjabi mixed vegetable pickle. It typically contains five or more vegetables: raw mango, lime, green chilies, carrot, cauliflower, turnip, and sometimes lotus stem (bhein) or ginger (adrak). The vegetables are mixed with salt, spices, and mustard oil, and fermented for 15 to 20 days. Panchranga achar is a staple in many Punjabi households.

Lehsun ki Chutney (Fermented garlic chutney)

Garlic chutney is made by crushing fresh garlic cloves with salt, chili powder, and a small amount of mustard oil, and then leaving the mixture to ferment for 5 to 7 days. The fermentation reduces the pungency of raw garlic (allicin degrades) and produces a sour, salty, intensely flavorful chutney. It is consumed in tiny quantities as a condiment with makki di roti, bajre ki roti, and dal. Lehsun ki chutney is very popular in Punjab, especially in the winter months.

Saunth (Fermented ginger and tamarind chutney, sometimes fermented)

Saunth is a sweet and sour chutney made from dried ginger (saunth), tamarind (imli), jaggery (gur), and spices. A fermented variation exists where the mixture is left to ferment for 2 to 3 days before bottling. The fermentation adds a complex tanginess. This product is rare.

---

Part 5: Fermented Beverages

Punjab's fermented beverage tradition is dominated by dairy based drinks (lassi, chaas). Non dairy fermented beverages are less common but include kanjhi and fermented rice water in some communities.

Lassi and Chaas (Already covered in Part 2)

Lassi and chaas are the primary fermented beverages.

Kanjhi (Fermented carrot beverage)

Kanjhi is made in Punjab, particularly in the winter months (December to February). Black carrots (or red carrots) are peeled, cut into pieces, and mixed with water, salt, mustard powder (rai), and asafoetida. The mixture is left to ferment in a glass or ceramic jar in the sun for 3 to 5 days. The fermentation is driven by LAB, primarily Lactobacillus plantarum and Leuconostoc species. The resulting kanjhi is a sour, spicy, effervescent, pinkish red beverage. It is consumed as a digestive drink and is also used as a home remedy for indigestion and flatulence. Kanjhi is a genuine probiotic beverage. It is particularly popular in the Majha region (Amritsar, Gurdaspur, Tarn Taran) and Doaba region (Jalandhar, Hoshiarpur, Kapurthala).

Fermented Rice Water (Pakhala or Kanji)

In some rural households, particularly in the Malwa region (Bathinda, Ludhiana, Patiala, Sangrur), fermented rice water is made. Cooked rice is mixed with water and left to ferment overnight (8 to 12 hours). The resulting liquid is consumed as a beverage, and the rice grains are eaten as a meal. This is similar to the Tamil "seepu" and the Odia "pakhala." It is a genuine probiotic beverage if not cooked. The fermentation reduces the glycemic index of the rice and adds B vitamins. This product is more common in rural areas and among agricultural laborers. It is called "kanji" or "peej" in some dialects.

Sattu ka Sharbat (Fermented variation)

Sattu (roasted chickpea flour) is typically mixed with water, lemon juice, salt, and roasted cumin powder to make a non fermented, non probiotic beverage. A fermented variation mixes sattu with sour buttermilk (chaas) instead of water, creating a fermented, probiotic, protein rich beverage called "sattu chaas."

Fermented Kanji (Bajre ka kanji, already covered in Part 1)

The thin fermented millet beverage is also consumed as a drink.

---

Part 6: Starter Cultures and Fermentation Vessels

Earthen pots (Matka, Ghada, Handi, Kulhad)

Traditional Punjabi households ferment dahi (curd) and store other ferments in unglazed earthen pots called matka, ghada, or handi. The porous inner surface retains a biofilm of LAB from previous batches, acting as a passive starter culture. In the extreme summer heat, the matka is kept in a cool, dark corner or covered with a wet cloth for evaporative cooling. In the cold winter, the matka is wrapped in a quilt (rajai) or placed near the hearth (chulha). Earthen cups called kulhad are used to serve lassi and chaas; the porous clay absorbs some liquid and imparts an earthy flavor. Matkas that have been used for decades are highly prized.

Wooden churn (Bilona or Madhanu)

Traditional Punjabi households use a wooden churn called "bilona" or "madhanu" to churn dahi to separate butter (makhan) and buttermilk (lassi/chaas). The bilona is a cylindrical wooden vessel with a wooden plunger (churning rod) that is rotated rapidly by pulling a rope wound around it. The wooden vessel retains a biofilm of LAB, contributing to the flavor of the butter and buttermilk. The bilona is often not washed with soap (only rinsed with water) to preserve the microbial community. This practice is still maintained in many rural households and is even making a comeback in urban homes as people seek traditional "bilona ghee" for health benefits.

Buttermilk (Chaas) and Yogurt (Dahi) as starters

For fermenting doughs (bajre ki roti, makki di roti, missi roti, thepla) and lentil batters (dahi bada, papad, vadi), sour buttermilk (chaas) or sour yogurt (dahi) is added as a starter culture. This ensures consistent fermentation, especially in the cold winter months when spontaneous fermentation is unreliable.

Jaman or Khatta Dahi (The sour curd starter)

Punjabi households maintain a reserved sour curd starter called "jaman" or "khatta dahi" (sour yogurt). A small amount is saved from each batch to inoculate the next batch. This starter is kept alive for years and is considered essential for good dahi. The jaman becomes progressively more sour as it ages. It is stored in a small earthen pot (katori) in a cool place. A good jaman is a family heirloom, passed down from mother to daughter.

Metal vessels (Modern adaptation)

In urban Punjabi households, stainless steel or glass vessels are often used for fermenting dahi and batters. While these are easier to clean, they do not retain a microbial biofilm like earthen pots, so the starter culture must be added fresh every time. The flavor of dahi set in metal vessels is different (less complex) than dahi set in earthen pots.

Final Safety and Consumption Note

While traditional fermented foods of Punjab offer significant nutritional and probiotic benefits, several safety considerations specific to the state's extreme climate and unique products should be noted.

For fermented flatbreads and grain products (bajre ki roti, makki di roti, fermented wheat roti, missi roti, thepla, raab, bajre ka kanji): These products are cooked (roti, raab) or fermented and consumed raw (bajre ka kanji). The cooked products are safe for everyone, including pregnant women, infants, and immunocompromised individuals. Raw fermented bajre ka kanji (the thin beverage) is a genuine probiotic food but carries a risk of contamination. Only kanji with a clean, sour smell (like yogurt) and no visible mold or slime should be consumed. Pregnant women and immunocompromised individuals should avoid raw fermented kanji and consume only cooked raab. Dough that has fermented for too long (more than 8 hours in summer, more than 20 hours in winter) may become excessively sour (vinegar like) or develop off flavors. A putrid smell, visible mold (green, black, pink), or slimy texture indicates spoilage, and the dough should be discarded. For makki di roti (corn flatbread), the dough is inherently brittle; if it becomes excessively sticky or sour, discard it.

For dairy products (dahi, lassi, chaas, makhan, ghee, kadhi, raita, khatta rabri): Dahi, lassi, chaas, makhan, and raita are genuine probiotic foods when consumed live (not heated). They are generally safe for healthy individuals and pregnant women. For immunocompromised individuals, live dairy ferments are generally safe, but consultation with a physician is advised. Kadhi, if gently heated (not boiled), retains some probiotics and is safe. Ghee (from cultured butter) is not probiotic (heating kills all microbes) but is safe for everyone. Dahi that has been stored for more than 5 to 7 days, or that shows signs of mold (green, black, or pink spots), should be discarded. In the extreme summer heat, dahi can become excessively sour (pH below 3.5) within 24 hours; this is still safe but may cause digestive discomfort in some individuals. Makhan (white butter) should be consumed fresh (within 2 to 3 days) as it spoils faster than dahi. If makhan develops a rancid smell (like old oil, or bitter, or cheesy) or a bitter taste, it should be discarded. Lassi and chaas should be consumed within 24 to 48 hours. If they develop a fizzy, effervescent quality (beyond the normal slight effervescence) or an off smell, discard them.

For fermented lentil and pulse products (papad, vadi, bari, mangodi, dahi bada, bhalla): Papad, vadi, bari, and mangodi are sun dried and then roasted or fried before eating; the high heat kills live microbes. They are safe for everyone. Ensure that sun drying is done in a clean, dust free environment (covered with a thin cloth) to prevent contamination from dust, insects, or bird droppings. If sun dried products develop visible mold (black, green, pink, white fuzzy) during storage, discard the entire batch. Dahi bada and bhalla: the deep fried bada are safe for everyone. The live yogurt (dahi) on dahi bada is safe for healthy individuals and pregnant women. Immunocompromised individuals should consult a physician before consuming live dahi.

For fermented pickles and condiments (aam ka achar, nimbu ka achar, hari mirch, gajar, gobhi shalgam gajar, panchranga achar, lehsun ki chutney, saunth): These products have a high salt content (10 to 20 percent) and high oil content (mustard oil). Individuals with hypertension, congestive heart failure, chronic kidney disease, or gallbladder disease should consume these pickles only in extremely small quantities or avoid them entirely. Pregnant women can consume in small amounts (a few pieces per meal), but excessive salt intake should be avoided. Pickles that develop a slimy texture, unusual colors, or a putrid, rotten smell should be discarded. A white film on the surface (kahm yeast) is not necessarily harmful but indicates air exposure; the yeast layer should be removed, and the pickle below should be checked for off odors. Mold growth (green, black, or pink) on the surface warrants discarding the entire batch. For lehsun ki chutney (garlic), the strong pungency can cause digestive discomfort in some individuals; start with a very small amount (less than a quarter teaspoon). Mustard oil pickles: mustard oil contains erucic acid, which is safe in tiny quantities (the amount consumed in a serving of pickle is negligible) but may cause issues if consumed in very large amounts.

For fermented beverages (lassi, chaas, kanjhi, fermented rice water, sattu chaas, bajre ka kanji): Lassi, chaas, sattu chaas, and fermented rice water (peej/kanji) are non alcoholic (alcohol below 0.5 percent) and safe for everyone, including pregnant women. Kanjhi (carrot kanjhi) is also non alcoholic and safe. Bajre ka kanji (the thin millet beverage) is non alcoholic but has the same safety note as raw fermented kanji above (avoid during pregnancy). These beverages should be consumed within 2 to 3 days (carrot kanjhi within 5 days, fermented rice water within 24 hours). Any beverage with a putrid smell, visible mold, or a thick slimy consistency should be discarded.

For individuals on monoamine oxidase inhibitor (MAOI) medications: Aged products such as long fermented pickles (aged for more than 6 months) and aged jaman (very sour curd starter) may contain elevated levels of tyramine. These individuals should avoid aged fermented foods or consult their physician. Freshly fermented products (fresh dahi, fresh lassi, fresh chaas, fresh kanjhi) have lower tyramine levels and are generally safe.

For general consumers: Start with small quantities of any new fermented food to assess individual tolerance. Fermented foods are generally safe for healthy individuals. Pregnant women, immunocompromised individuals, and infants under one year should consult a physician before adding significant quantities of live fermented foods (raw dahi, raw lassi, raw chaas, raw makhan, raw kanjhi) to their diet. For cooked fermented products (bajre ki roti, makki di roti, raab, kadhi, papad, vadi, mangodi, dahi bada (the bada part only)), no consultation is needed as these are safe for everyone.

Note on Commercial Products: Many commercially available dahi, lassi, chaas, kadhi, papad, and pickles are pasteurized or contain preservatives. These products do not contain live probiotics. For probiotic benefits, traditional, homemade, or fresh (non pasteurized) products are required. For dahi, lassi, and chaas, look for "live cultures" or "contains active bacteria" on the label. For pickles, traditional sun fermented pickles are more likely to contain live microbes than mass produced, heat processed pickles. For makhan (white butter), commercially available white butter is often pasteurized; only fresh, homemade, cultured butter contains live probiotics. For bilona ghee (ghee made from cultured butter), the ghee itself is not probiotic, but it is nutritionally superior to ghee made from fresh cream. Look for "bilona ghee" or "cultured ghee" on labels.

Note on Extreme Summer and Winter: The extreme seasonal variations in Punjab significantly affect fermentation. In summer (40 to 45 degrees Celsius), fermentation happens very rapidly (3 to 4 hours for dahi, 4 to 5 hours for dough). Check ferments earlier than usual to prevent over fermentation. In winter (0 to 5 degrees Celsius), fermentation is very slow (12 to 16 hours for dahi). Use a warm spot (near the hearth, inside a quilt, inside the oven with the pilot light, or on top of a water heater) and increase the amount of starter culture by 50 percent. Fermentation may fail if the temperature drops below 15 degrees Celsius for extended periods; in such cases, households often skip fermentation or use commercial starter packets. In the winter, some households also use a "surahi" (a porous earthen pot with a narrow neck) placed near the hearth to maintain a stable warm temperature for dahi setting.
