Tadka Buttermilk is a refreshing and flavorful Indian beverage made from buttermilk that has been seasoned with a tempering of spices and herbs.

To prepare Tadka Buttermilk, buttermilk is typically seasoned with a tempering (tadka) of spices like mustard seeds, cumin seeds, curry leaves, green chilies, and sometimes grated ginger. This tempering is prepared separately in ghee or oil until the spices release their aroma and the mustard seeds start to splutter. The tempered spices are then added to the buttermilk and mixed well.

The result is a tangy, savory, and slightly spicy drink that is both refreshing and satisfying. Tadka Buttermilk is often served chilled and garnished with fresh cilantro leaves or mint leaves for added flavor and aroma. It's a popular beverage in Indian cuisine, enjoyed as a refreshing drink on its own or served alongside meals to aid digestion and balance the palate after consuming spicy foods.
