It is derived from the split and skinned version of the pigeon pea, offering a rich nutty flavor and a creamy texture when cooked. Arhar dal is a staple ingredient in dishes like dal tadka and sambar, providing a good source of protein, fiber, and essential nutrients. It cooks relatively quickly and pairs well with rice or bread for a satisfying meal.
