They are typically dry and brittle with longitudinal ridges on their surface. Coriander seeds have a warm, citrusy, and slightly sweet flavor with a hint of spice. The aroma is aromatic and earthy. The flavor of coriander seeds changes slightly when they are toasted or ground. Coriander seeds are used whole or ground in cooking. They are a common spice in Indian, Middle Eastern, European, and Asian cuisines. Whole coriander seeds are often used in pickling, sausages, curries, soups, and stews. Ground coriander is used in spice blends, marinades, and rubs for meats and vegetables.
