Naan is a leavened bread made from maida, a very delicate and powdery Indian white flour, similar to pastry meal. It is most commonly eaten with curry, used to sop up all of the sauce and pick up vegetables instead of a spoon. It is sometimes flavoured with nigella seeds — black seeds with a slightly astringent flavour found in Indian grocery stores and are often incorrectly referred to as "onion seeds," "black sesame," or "black cumin."
