Transform leftover kadhi into a delightful and savory snack with Khandvi. This Gujarati delicacy is made by cooking a thin batter of besan (gram flour) and yogurt, which is then rolled into thin, bite-sized rolls. The rolls are seasoned with a tempering of mustard seeds, curry leaves, and grated coconut, adding a burst of flavors to the dish. Serve these soft and tangy rolls as an appetizer or tea-time snack.
