Nigella is a genus of about 14 species of annual plants in the family Ranunculaceae, native to southern Europe, north Africa, south and southwest Asia. Common names applied to members of this genus are nigella, devil-in-a-bush or love in a mist.
The seeds of Nigella sativa, known as kalonji, black cumin (although black cumin may also refer to Bunium persicum), black onion seed, onion seed or just nigella, are used as a spice in Indian and Middle Eastern cuisines. The dry-roasted nigella seeds flavor curries, vegetables and pulses. The black seeds taste like a combination of onions, black pepper and oregano, and have a bitterness to them like mustard seeds. It can be used as a "pepper" in recipes with pod fruit, vegetables, salads and poultry.
