Plain black urad dal, also known as kaali dal or mah ki dal, is a rich and creamy lentil dish made from whole black gram lentils (urad dal) without any additional ingredients like tomatoes, onions, or spices.

To prepare plain black urad dal, the lentils are soaked overnight and then cooked until soft and creamy. The cooked dal is then tempered with ghee (clarified butter) and seasoned with salt. Some variations may include a tadka (tempering) of cumin seeds, garlic, and green chilies for added flavor, but the dish is typically kept simple to highlight the natural creaminess and earthy flavor of the black urad dal.

Plain black urad dal is often served hot with rice or Indian flatbreads like roti or naan. It's a comforting and nutritious dish that is popular in North Indian cuisine and is enjoyed for its rich flavor and creamy texture.
