Whole coriander seeds are the dried seeds of the coriander plant (Coriandrum sativum). They have a warm, citrusy, and slightly spicy flavor, commonly used in cooking and spice blends. Whole coriander is often used to enhance the taste of curries, stews, soups, and pickles. The seeds can be ground for a more intense flavor or used whole in cooking to impart a mild, aromatic essence. Whole coriander seeds are also popular in Indian, Middle Eastern, and Latin American cuisines.
