Coriander (Coriandrum sativum) is an annual herb in the family Apiaceae. It is also known as Chinese parsley, and in North America the stems and leaves are usually called cilantro. All parts of the plant are edible, but the fresh leaves and the dried seeds (as a spice) are the parts most traditionally used in cooking.
The fragrant, pungent leaf of the coriander plant, cilantro is popular in Mexican, Thai and Vietnamese cooking. Try its distinct, parsley-sage flavor in salsas, sauces and soups, especially in tandem with chilies.
