Yellow moong dal refers to moong beans that have been skinned and split, so that they're flat, yellow, and quick-cooking. They're relatively easy to digest. They can be made into moong bean paste by de-hulling, cooking, and pulverizing the beans to the consistency of a dry paste. Mung dal is the split and washed mung bean, and looks like a small, plump, yellow split pea. Mung dal is used to make a creamy and delicious dal that is a daily staple of the Indian sub-continent.
