Tadka Dal is a popular Indian dish made primarily from lentils, often yellow split peas or red lentils. The lentils are cooked until soft and then seasoned with spices, creating a flavorful and nutritious meal. It is commonly served with rice or flatbreads like roti or naan. The dish gets its name from the "tadka," which refers to the tempering process where spices such as cumin, mustard seeds, and garlic are sautéed in oil or ghee. This technique enhances the flavor of the dal, making it a staple in many Indian households and a favorite in restaurants.
