Nigella is a seed spice from a herbaceous annual of the buttercup family. The triangular seeds are held in a seed head similar to a poppy head. Nigella seeds have little aroma but when rubbed give off a peppery smell with hints of oregano. The taste is nutty, earthy, and herb-like. 

Use in pilafs, curries and pickles. The seeds are often dry roasted or fried to bring out their full flavour. In the Middle East nigella seeds are sprinkled over breads and cakes, and in Iran it is a popular pickling spice for fruit and vegetables.
