Coriander seeds are small, round seeds that come from the coriander plant. These seeds have a mild, slightly sweet flavor and are commonly used in cooking to add an earthy taste to dishes such as curries, stews, and salads. They can also be used to make tea or brewed as a coffee substitute. In addition to their culinary uses, coriander seeds have been used for medicinal purposes throughout history due to their anti-inflammatory and digestive properties.
