Also known as black cumin, kalonji or black onion seed, these tiny black seeds are used as a spice in Indian and Middle Eastern cuisine. They have a slightly bitter, savoury pepper flavour which disappears and becomes sweeter once the seed is lightly toasted in a dry pan. Kalonji is popular in India where the seed is grown and is used to flavour naan bread, pickles and curry pastes. It can be used as a "pepper" in recipes with fruit, vegetables, salads and poultry.
