Naan is a soft, leavened flatbread originating from South Asia, particularly India and Pakistan. It's typically made from refined flour, yeast, water, and sometimes yogurt or milk. The dough is stretched and slapped onto the walls of a tandoor oven, where it bakes quickly, puffing up and developing a slightly charred exterior. Naan is often served hot and brushed with butter or ghee, making it a delicious accompaniment to curries or grilled dishes.
