We eat this form of moong dal more than any other in our Punjabi homes. I know you’ve seen the roundish green moong, which is the original form of this legume. I call it a legume because even though it looks like a lentil, it’s really a bean. Why it’s common to hear ‘moong bean’ but calling this form above a bean would be confusing because it looks flat and roundish like a lentil split in half and without the green outer skin. Whenever you see the word duhli on packaging, it indicates a legume is ‘washed’ – no skin and usually split.
