Dahi Kanji is a traditional Indian fermented drink made with carrots, mustard seeds, and yogurt. It is a tangy and spicy drink that is popular during the festival of Holi. The carrots are pickled in a mixture of water, mustard seeds, and spices, and then mixed with yogurt to create a refreshing and probiotic-rich beverage. Dahi Kanji is not only delicious but also aids in digestion and boosts the immune system.
