Black Cumin (Kalonji seeds) come from a plant called Nigella sativa native to southern Europe and western Asia. The little tear-shaped black seeds, about 1 mm long, are used throughout as a spice and flavouring. They have an earthy, peppery taste, a little like oregano. The whole or crushed seeds are often mixed through dough or sprinkled on bread, giving the bread a black colour. The seeds are also used to flavour a variety of dishes ranging from sauces, curries, pickles and meat dishes to vegetables and fruit pies.
