The '''black gram''' or '''urad bean'''{{efn|Also known as the urid bean, minapa pappu, black matpe, matimah, matikolai, mash kalai, maas/kalo daal, uzhunnu/ulundu parippu, or uddu}} (''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.

==Description== It is an erect, suberect or trailing, densely hairy, annual bush. The tap root produces a branched root system with smooth, rounded nodules. The pods are narrow, cylindrical and up to {{Convert|6|cm|frac=4}} long. The plant grows {{Convert|30–100|cm|abbr=on}} tall with large hairy leaves and 4–6&nbsp;cm seed pods.<ref name=":0">{{Cite web |url=http://agmarknet.nic.in/BlackGram1.pdf |title=Post Harvest Profile of Black Gram |date=2006 |publisher=Government of India, Ministry of Agriculture |access-date=11 December 2014 |archive-date=21 November 2014 |archive-url=https://web.archive.org/web/20141121021830/http://agmarknet.nic.in/BlackGram1.pdf |url-status=dead }}</ref>

''Vigna mungo'' is popular in Northern India, largely used to make ''dal'' from the whole or split, dehusked seeds. The bean is boiled and eaten whole or, after splitting, made into ''dal''; prepared like this it has an unusual mucilaginous texture.

Fermented ''Vigna mungo'' paste is also used to prepare ''Lakhnapuri Bhalle'' or ''Lakhanpuri Laddu'' (a popular street food of Jammu region).

In Uttarakhandi cuisine, ''Vigna mungo'' is used for preparing traditional dish called ''Chainsu'' or ''Chaisu''.

In North Indian cuisine, it is used as an ingredient of ''Dal makhani,'' which is a modern restaurant style adaptation of Traditional ''Sabut Urad Dal'' of Northern India.

In Bengal, it is used in ''kalai ruti'', ''biulir dal''. In Rajasthan, It is one of the ingredients of ''Panchmel dal'' which is usually consumed with ''bati''. In Pakistan, it is called ''' Dhuli Mash ki daal''' <ref>[https://web.archive.org/web/20240620211654/https://mrecipezone.com/daal-mash-urad-dal/ | Dhuli Mash ki Daal]</ref> and used to make '''laddu Pethi walay''' and '''Bhalla'''.

It is also extensively used in South Indian culinary preparations. Black gram is one of the key ingredients in making idli and dosa batter, in which one part of black gram is mixed with three or four parts of idli rice to make the batter. Vada or udid vada also contain black gram and are made from soaked batter and deep-fried in cooking oil. The dough is also used in making papadum, in which white lentils are usually used.

In the Telugu states, it is eaten as a sweet in the form of laddoos called Sunnundallu or Minapa.
