Naan is an Indian flatbread made from wheat dough, which is traditionally baked against the side of a tandoor oven and then coated with ghee (clarified butter). It is often served as a side dish to curries and other main meals.
Naan is leavened, oven baked flatbread, it resembles pita bread but unlike pita, it has yogurt, milk, sometimes eggs or butter which makes it softer than the pita bread.
Try it by ordering it in an Asian/Indian restaurant, you will be surprised how delicate and soft it is.
