The black gram or urad bean[a] (Vigna mungo) is a bean grown in South Asia. Like its relative the mung bean, it has been reclassified from the genus Phaseolus to Vigna. The product sold as black gram is usually the whole urad bean, whereas the split bean (the interior being white) is called white lentil. It should not be confused with the much smaller true black lentil (Lens culinaris).
Black gram originated in South Asia, where it has been in cultivation from ancient times. It is very widely used in South Asian cuisine. In India the black gram is one of the important pulses grown in both kharif and rabi seasons. This crop is extensively grown in the southern part of India and the northern part of Bangladesh and Nepal. In Nepal it is known as maas and mash daal in Bangladesh. It is a popular daal (legume) side dish in South Asia that goes with curry and rice as a platter. Black gram has also been introduced to other tropical areas, such as the Caribbean, Fiji, Mauritius, Myanmar and Africa, mainly by Indian immigrants during the Indian indenture system.
