Naan is a soft and fluffy leavened Indian flatbread that comes from the Persian word "non," or bread. It is typically made with ingredients like flour, yeast, yogurt, milk, and sometimes eggs or ghee (clarified butter). Naan is often tear-drop shaped and puffs up as it cooks. It was traditionally baked in a tandoor, a clay oven, but is commonly baked in an oven, cooked over high heat in a cast iron skillet or frying pan, or even grilled.
