Don't mistake these small, black nigella seeds for black onion seeds, black cumin or black caraway! Nigella seeds are very much their own. They are hard and crunchy with a flavour like toasted onions adding wonderful aroma to traditional Turkish and Moroccan breads and Indian naans. Nigella is also used to flavour sweets, liqueurs and cheeses in Arabic cooking and can be added to vegetables or sprinkled on fish prior to grilling. They are also one of the five spices that make up panch poran, a spice mixture from Bengal.
