Fermented Foods in India: The Regional Guide to Every Probiotic Food

What Are the Fermented Foods in India?

India has more than 50 traditional fermented foods. Ten of them cover most Indian kitchens. They are curd, lassi, idli and dosa batter, appam batter, dhokla, salt-sun pickle, kanji, pakhala, gundruk and hawaijar. Only the ones you eat raw still carry live bacteria. Anything steamed or fried loses its cultures on the stove. It keeps the extra B vitamins all the same.

1. Curd (dahi) — the fermented food Indians eat most. Codex sets the floor for a fermented milk at 10 million live starter bacteria per gram, held to the date on the pack.
2. Lassi and chaas — churned curd. It keeps the live cultures of the curd it came from, because nothing is heated.
3. Idli and dosa batter — rice and urad dal soured overnight by lactic acid bacteria. Steaming or frying kills those bacteria, so the live benefit sits in the raw batter.
4. Appam batter — rice and coconut soured with toddy, so it carries yeast as well as lactic acid bacteria.
5. Dhokla — soured chickpea batter, then steamed. Same rule as idli: the B vitamins stay, the live cultures do not.
6. Salt-and-sun pickle (achar) — oil-free pickle soured in brine. Salt clears the way for Lactobacillus and little else.
7. Kanji — a Punjabi black-carrot and beetroot drink, drunk raw, tart and deep purple.
8. Pakhala — Odia rice soaked in water overnight and eaten cold the next day, cultures intact.
9. Gundruk — Himalayan soured leafy greens. Tamang and colleagues counted lactic acid bacteria at the level of 10 million per gram across 25 gundruk samples.
10. Hawaijar — Manipuri soured soybean. Jeyaram's team found Bacillus the dominant genus in 41 samples from Manipur households and markets.

What Makes a Food Truly Probiotic?

A probiotic is a live microorganism that gives a health benefit when you eat enough of it. That is the wording of the ISAPP expert consensus (Hill et al., 2014). So a probiotic food has to reach your gut with the bacteria still alive. Many Indian foods are fermented but not probiotic, because the bacteria die in the cooking. The test is simple: are the cultures alive when you eat it, or only while it was souring?

Indians eat fermented food every day. Curd, idli batter, dosa batter, pickle, kanji, dhokla: souring is built into the way we cook. But these foods are not equally probiotic. Idli loses its live cultures in the steamer. Fresh curd keeps them.

Complete Map of Indian Fermented Foods by Region

India has more than 50 traditional fermented foods, and every region has its own. North India has kanji and lassi. South India has idli batter and appam. West India has dhokla and sol kadhi. East India has pakhala and tungrymbai. The Northeast has hawaijar, gundruk and kinema. Each one grew out of the local climate, the local crop and the need to keep food from spoiling.

Pan-India

Curd (dahi): The probiotic food Indians eat most. Codex names the yoghurt starter pair as Streptococcus thermophilus with Lactobacillus delbrueckii subsp. bulgaricus. Indian dahi adds wild strains carried over from the last batch. A curd maker (Rs 1,199, sold out on 11 September 2026) holds the temperature steady so the cultures grow evenly. The Greek Yogurt Maker at Rs 999 is in stock and does the same job.

Pickles (achar): An old-style pickle soured in salt and sun is genuinely probiotic. A shop pickle packed in oil with preservatives is not. Salt makes a place where little survives except Lactobacillus.

North India

Kanji: A soured carrot and beetroot drink from Punjab. It is drunk raw, so the cultures reach you alive. Deep purple, sharply tart, and one of India's most overlooked probiotic foods.

Lassi: Churned curd. Nothing is heated, so it keeps the live cultures of the curd. Sweet or salted, it tastes like a treat and works like curd.

South India

Idli and dosa batter: Rice and urad dal sour overnight, the work of Leuconostoc and Lactobacillus. Steaming the idli kills those cultures. A hot tawa kills most of them too. The value sits in the raw batter, not the plate.

Appam batter: Rice and coconut soured with toddy, so it holds yeast as well as lactic acid bacteria. Cooking cuts the live count again.

Northeast India

Hawaijar (Manipur): Soured soybean paste, eaten as a condiment with rice. Jeyaram and colleagues typed 274 isolates from 41 samples. Bacillus was dominant, and the B. subtilis group made up 112 of them (Int J Food Microbiol, 2008). It costs almost nothing in a Manipuri market.

Gundruk (Sikkim): Soured leafy greens, eaten as a side dish or in soup. Tamang and colleagues counted the bacteria in 25 samples and found them at the level of 10⁷ per gram (Int J Food Microbiol, 2005). The species they named:

• Lactobacillus brevis
• Lactobacillus plantarum
• Pediococcus pentosaceus
• Pediococcus acidilactici
• Leuconostoc fallax

Tungrymbai (Meghalaya): Soured soybean from Khasi kitchens. Like hawaijar, it is a Bacillus ferment rather than a lactic one.

East India

Pakhala (Odisha): Rice soaked in water overnight and eaten cold the next day. The souring is the work of Lactobacillus and Leuconostoc. It is a summer meal that doubles as a probiotic, served with fried vegetables and curd.

West India

Dhokla: Soured chickpea batter steamed into soft cakes. The souring grows lactic acid bacteria, but the steamer kills most of them. The extra B vitamins stay.

Sol kadhi: A coconut milk and kokum drink from Goa and Maharashtra. Only lightly soured, so it is not a strong probiotic. It is still drunk after a meal to settle the stomach.

Which Indian Foods Have the Best Probiotic Strains?

Homemade curd, kanji and gundruk carry the most value. All three are eaten raw, so the cultures are still alive when you swallow them. Curd runs on Lactobacillus and Streptococcus. Kanji is a raw Lactobacillus drink. Gundruk was measured at the level of 10 million lactic acid bacteria per gram (Tamang, 2005).

Why Homemade Curd Beats Store-Bought

Fresh homemade curd carries more live cultures than most packet curd, and the rule book explains why. The Codex standard for fermented milk asks for at least 10⁷ live starter bacteria per gram, right up to the date on the pack. But it then says the viability rule "does not apply" if the product is heat-treated after fermentation (CXS 243-2003). Heating after souring buys shelf life and costs live bacteria. Curd you set at home is never heated afterwards, so nothing kills the cultures. Set it at about 42 degrees Celsius for 8 to 10 hours.

Set side by side, home curd from our Greek Yogurt Maker (Rs 999, September 2026) is thicker and sharper than a packet curd of the same age. We have not counted bacteria in a lab, so treat the taste as taste. The label is what tells you the rest: look for a line saying the curd contains live cultures, and be wary of a very long shelf life.

How to Get Probiotics Daily from Indian Food

A workable day looks like this. Curd at breakfast. A glass of lassi or chaas at lunch. A spoon of salt-sun pickle with dinner. Kanji in the evening. Four different sources beat four helpings of the same one, because each food brings its own strains.
