Besan is a flour made from ground chickpeas, a legume otherwise known as chana dal. It is also known as chickpea flour, garbanzo flour, or besan. Used in many countries, it is a staple ingredient in Indian, Pakistani and Bangladeshi cuisines, and, in the form of a paste with water or yoghurt, a popular facial exfoliant in the Indian Subcontinent. Moreover, when mixed with an equal proportion of water, can be used as an egg-replacer in vegan cooking.
