The seeds of Nigella sativa are used as a spice in Indian and Middle Eastern cuisines. The black seeds taste like a combination of onions, black pepper and oregano. They have a pungent bitter taste and smell.
The dry-roasted nigella seeds flavor curries, vegetables and pulses. It can be used as a "pepper" in recipes with pod fruit, vegetables, salads and poultry. It is used as part of the spice mixture panch phoron (meaning a mixture of five spices) and by itself in many recipes in Bengali cuisine and most recognizably in naan bread. Nigella is also used in Armenian string cheese, a braided string cheese called majdouleh or majdouli in the Middle East.
