Naan is a leavened oven baked Indian flat bread popular in India as well as whole world. We go to any Indian restaurant and look at menu, we find Naan mentioned where all flat breads are listed in menu. It is a perfect combination to order with any type of curry. Naan is fundamentally different from another very popular Indian flat bread called Chapati. Traditionally naan bread is cooked in a tandoor that is clay oven from which tandoori cooking takes its name while Chapati is cooked directly over flames using a pan.
