Offering nourishing sources for gut health and immunity through fermentation, idli, dosa, and kanji will allow for a flow of good health during the winter months while providing familiar, comforting foods.
This article outlines the importance of how traditional Indian fermentation methods provide nourishment for our gut through improved digestion and enhanced immunity to the cold of winter. It will give you ways to make fermented foods like idlis and dosas part of your winter routine without making cooking harder.
Your body's digestive process will slow down during the winter months, and, therefore, you may become less resistant to infection. You can improve your resistance and body function with the use of fermented foods that provide your body with active cultures or probiotics. This, in turn, maintains the balance in your gut and provides for smooth digestion.
The tradition of using fermented foods during winter is deeply ingrained in the culture of India. From mildly fermented dosa to spongy yeasted idli to tangy pink kanji, fermented foods are both comforting and energising at the same time.
While idlis may appear simple, they are actually teeming with microorganisms. The fermentation of the batter overnight captures the lactic acid bacteria that assist in the breakdown of carbohydrates and proteins in the idlis, resulting in an easily digestible product, which is beneficial during the winter months. Secondly, idlis have the ability to warm one's body in a gentle manner. Consuming them warm with sambar or drizzled with a mixture of podi and ghee creates a unique experience that provides both satisfaction and lightness.
Pro-tip: To achieve even fluffier idlis, allowing the batter to ferment an extra couple of hours in the winter can help enhance flavour due to the slower process of fermentation.
Like idlis, dosas are also a source of probiotics but have a crispier texture than these steamed breads. This is because the batter ferments longer, adding complexity to the tanginess of the dosa. When eaten in winter, the mild tang of the dosa creates an immediate experience of comfort and warmth. The sound and movement of the dosa as it hits the hot pan awaken your body. Dosai fermentation increases the availability of B vitamins, which regulate the body's metabolism during times of energy fluctuation caused by coldness.
It is not uncommon to cook dosas, thukdas, and uthappams using the same batter. The favourable properties of the microbes in the batter still apply regardless of shape.
Nobody talks about kanji until you've developed a little snotty nose from cold weather. This bright purple beverage is created from fermented black carrot juice, mustard seed and water. Kanji has a tangy, earthy flavour and is made with gut-friendly probiotics.
The combination of natural probiotics and mustard creates a warming sensation as you drink this right after it is made. By drinking a small amount every day, your gut health and immunity will both improve without you even realising it. Kanji is incredibly low maintenance; simply mix all 3 ingredients, cover them up and place them in direct sunlight, and it will ferment on its own. If you're feeling heavy after eating lots of hearty foods this winter, kanji is a great way to "reset" your stomach.
The most effective method for incorporating fermentation into your daily life is to consider it a friend. Do not treat it as something special (like a health ritual). Each week, make a batch of batter for the next week's recipe, rotating between lentil-based dishes (idli, dosa, uttapam) and small amounts of kanji with an early evening meal. To ensure that the beneficial bacteria stay alive, always store leftovers slightly warm. On winter mornings, pair your fermented foods with either ghee or warm chutneys to counteract the cold temperatures of the season. No need for expensive probiotic supplements or dietary pills when it's all readily available in your kitchen.
In India, many uncommon fermented foods are perfect for the colder months that you may not have had the chance to try, as they are less well-known than the popular idli and dosa dishes. The fermented Handvo batter combines lentils, rice and a long fermentation time to build up all the proteins and beneficial bacteria for your gut to create a warm baked good with a crispy outer crust. Khaman Dhokla is another Gujarati dish that you can find more often in the Indian deserts due to the multiple ways of fermenting it to create this spongy snack that is served along with kadhi or chutney.
Fermented rice water, a common Kerala breakfast option, Pazham Kanji, is easy to warm up each morning and make for a nice breakfast before heading out to work. Gundruk is a traditional fermented leafy vegetable from the Northeastern states of India, and it is very warming and nourishing in the cold winter months because of the amount of acid created during the fermentation process. Pej is made from the fermentation of boiled and ground rice that is soaked overnight, then made into a drink that provides warmth as well as nutrition in the morning. If you enjoy having spicy foods, fermented bamboo shoots from Assam will provide beneficial gut bacteria and will add flavour and depth to soups and stews, even though they have a strong taste and aroma.
