There is a particular kind of aroma that announces some of Meghalaya’s most distinctive foods before they reach the table. It can be earthy and deeply savoury in fermented soybean, sharply acidic in preserved bamboo shoots, or intensely pungent in fermented fish. To an unfamiliar diner, these flavours can initially seem challenging. Within the Khasi, Jaintia and other food traditions of the state, however, they belong to a culinary vocabulary built over generations.
Fermentation in Meghalaya is not a recent experiment inspired by the global enthusiasm for kombucha, kimchi or sourdough. It developed as part of an indigenous food system shaped by landscape, seasonality and the need to preserve ingredients. Meghalaya’s official tourism literature describes fermentation as central to the state’s culinary identity, alongside smoking, cooking in bamboo, alkaline cooking and traditional stone cooking.
When time becomes an ingredient
At its simplest, fermentation allows microorganisms to transform food. Yet reducing the practice to microbiology misses much of its cultural meaning. Across the Eastern Himalayas, communities developed sophisticated fermented foods long before microorganisms themselves were scientifically understood. Research on the region describes more than 200 varieties of ethnic fermented foods and beverages, using ingredients ranging from soybean and bamboo shoots to vegetables, cereals, fish and meat.
In Meghalaya, this knowledge historically offered a practical response to abundance and scarcity. Seasonal ingredients could be preserved beyond the brief period in which they were harvested, while fermentation created flavours impossible to achieve with the fresh ingredient alone.
Bamboo shoot illustrates this relationship particularly well. Tender shoots are highly seasonal, but fermentation extends their life considerably. An ICAR account from Ri-Bhoi records a traditional method in which tender shoots are peeled, sliced and submerged in water in large jars. Fermentation begins after several days, producing the characteristic strong aroma. The preserved shoots can subsequently be used in curries, soups, pickles and chutneys throughout the year.
What began as preservation therefore became something more enduring: preference. The fermented ingredient was no longer merely a substitute for the fresh one. It acquired an identity of its own.
The unmistakable tungrymbai
Few foods represent this better than tungrymbai, Meghalaya’s fermented soybean preparation.
Soybeans are transformed through fermentation before being cooked into a richly aromatic dish. In Khasi cooking, tungrymbai may accompany rice and other dishes, and Meghalaya Tourism notes its pairing with black sesame seeds. Its flavour is robust and savoury, providing an intriguing contrast to a cuisine otherwise known for relatively restrained use of spices and oil.
Tungrymbai also belongs to a much larger fermented-soybean tradition across Northeast India and the eastern Himalayas. Similar community-specific foods include kinema in Sikkim, hawaijar in Manipur and axone or akhuni in Nagaland. The Department of Biotechnology specifically identifies tungrymbai as Meghalaya’s traditional fermented soybean food.
The similarities reveal something important about the region’s food history. Fermentation was not an isolated culinary trick but a body of practical knowledge that communities adapted to local ingredients, tastes and environments.
Bamboo bottled for another season
Fermented bamboo shoots tell another story of resourcefulness.
Bamboo is woven deeply into everyday life across much of Northeast India, and its young shoots are also valued as food. Once fermented, their fresh vegetal character develops into something sharper and more assertive. Meghalaya Tourism lists pickled bamboo shoots alongside tungrymbai when describing fermentation as one of the state’s characteristic indigenous preparation techniques.
The process also demonstrates the logic behind traditional preservation. ICAR records that the difficulty of obtaining bamboo shoots throughout the year encouraged their preservation through fermentation among Khasi communities. Instead of allowing a seasonal surplus to disappear, households could effectively bottle part of one season for another.
That is why the jar deserves as much attention as the finished curry. Fermentation transformed household storage into a quiet form of food security.
Fish with another life
Meghalaya’s fermentation story does not end with plants.
Tungtap, a fermented fish preparation associated with Meghalaya, introduces another powerful dimension to the table. Meghalaya Tourism describes fermented dry-fish chutney eaten with boiled potatoes, where the pungency of the fish is balanced by the comparatively gentle sweetness of the potato. The Department of Biotechnology also lists tungtap among the traditional fermented fish foods of Northeast India and identifies it with Meghalaya.
Together, soybean, bamboo shoot and fish demonstrate the extraordinary range of fermentation. The same underlying principle can transform ingredients with completely different textures and compositions, creating foods that bear little resemblance in aroma or flavour to where they began.
Knowledge without a cookbook
Perhaps the most fascinating ingredient in these foods is the one that cannot be bought: experience.
Traditional fermentation depends upon accumulated knowledge — recognising the right raw material, preparing it correctly, allowing sufficient time for transformation and knowing through smell, texture and appearance when it is ready. Historically, much of this expertise has moved between generations through practice rather than formal recipes.
Modern science is now examining what households understood empirically. Researchers studying traditional fermented foods from Meghalaya have isolated microorganisms and investigated their technological and potential probiotic characteristics. A 2026 scientific review similarly describes Northeast India’s fermented-food heritage as the product of centuries of cultural knowledge and adaptation to local environments.
There are also efforts to bring scientific standardisation to traditional practices without abandoning the foods themselves. The Department of Biotechnology has reported work on improved and hygienic production processes for tungrymbai and chubitchi, a fermented rice beverage, along with training involving 250 beneficiaries.
This intersection between inherited knowledge and food science could become increasingly important. Traditional fermentation deserves preservation, but commercial expansion also raises questions of hygiene, consistency and whether standardisation might gradually flatten the differences that make household and community recipes distinctive.
More than preserved food
The renewed global fascination with fermented food makes Meghalaya’s traditions feel strikingly contemporary. Yet viewing tungrymbai merely as a local equivalent of fashionable fermented products would miss the larger story.
These foods emerged from particular landscapes and ways of living. Meghalaya’s terrain and biodiversity encouraged communities to gather seasonal bamboo shoots, mushrooms, edible ferns, roots, herbs and other produce. Preservation techniques evolved alongside that intimate knowledge of what the surrounding environment could provide.
Fermentation was therefore never simply about keeping food from spoiling. It was about stretching a harvest across seasons, creating flavour from time, and passing practical knowledge from one kitchen to another.
That heritage remains alive whenever fermented soybean is slowly turned into tungrymbai, a jar of bamboo shoot is opened months after the harvest, or the unmistakable intensity of tungtap accompanies a meal.
In Meghalaya, some of the most interesting cooking happens before the fire is lit. The cook provides the ingredient, tradition provides the method — and time does the rest.
