Wikipedia Article About Urd Bean on Wikipedia Urd, urd bean, urad, urid, black gram, black lentil or white lentil (Vigna mungo) is a bean grown in southern Asia. It is largely used to make dal from the whole or split, dehusked seeds. It, along with mung bean was placed in Phaseolus but has been transferred to Vigna. It was at one point considered to belong to the same species as mung bean. The product known as "black lentils" is usually the whole urd bean or urad dal. The product known as "white lentils" is the same lentil with the black skin removed.
