Kalai Dal |Biulir Dal |Urad Dal
Kalai dal, Vigna mungo, the black gram, urad bean, minapa pappu, mungo bean or black matpe bean is a bean grown in the South Asia. Like its relative, the mung bean, it has been reclassified from the Phaseolus to the Vigna genus. The product sold as black lentil 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.
Kalai dal or 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.
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.
It is very popular in Punjabi cuisine as an ingredient of dal makhani. In Bengal, it is used in biulir dal. In Rajasthan.
