The dry fruit are known as coriander seeds or simply as coriander. They have a lemony citrus flavour when crushed, due to the presence of the terpenes linalool and pinene. It is also described as warm, nutty, spicy, and orange-flavoured. They are usually dried but can be eaten green. Ground coriander is a major ingredient in curry powder, certain Belgian-style beers and other aromatic dishes.
If the spice is bought whole in a non-dried form, it can be dried in the sun. Most commonly, it is bought as whole dried seeds, but can be bought in ground form. Store coriander seed in a tightly sealed container away from sunlight and heat. For maximum flavour use within 6 months and keep for no more than 1 year. It can be roasted or heated on a dry pan briefly to enhance the aroma before grinding it in an electric grinder or with a mortar and pestle; ground coriander seeds lose their flavour quickly in storage and are best only ground as needed.
Coriander seed is a key spice in garam masala and Indian curries, which often employ the ground fruits in generous amounts together with cumin.
