Corriander leaves are an aromatic spice with a fresh, citrus flavor. They are often used in Mexican, Indian, and Thai cuisine. The leaves are also used in the Middle East to flavor kebabs and other meat dishes. Corriander leaves can be used fresh or dried. To use fresh leaves, remove the stems and wash them thoroughly. Fresh leaves should be added to dishes near the end of cooking to maintain their flavor. Dried leaves can be added to dishes at the beginning of cooking.
