While cilantro and coriander both come from the Coriandrum Sativum plant, they are two different spices. Cilantro comes from the seeds of the coriander plant, and the dried seeds of this same plant are known as coriander seeds. Cilantro is an herb with a distinctive citrus flavor, and coriander seeds are a spice with a spicy, nutty flavor. Coriander is more similar to cinnamon or cumin. You can add cilantro to recipes for chutney, guacamole, salsa, and soups. Curries, rice dishes, meat rubs, and pickled vegetables use coriander.
