Taak, also known as buttermilk, is a traditional Indian drink that is made from the liquid residue of churned yogurt or curd. It is typically made by mixing yogurt or curd with water and then churning it to separate the liquid from the solid. The liquid that remains is called Taak. It is a popular drink in India, particularly during the summer months, as it is cool and refreshing. It is also considered to have many health benefits, such as aiding digestion, providing hydration, and helping to cool the body. It can be enjoyed plain or with a variety of spices and herbs such as cumin powder, ginger, and mint leaves.
