This aromatic leaf is called fresh coriander to distinguish it from its seeds, the spice. It is also called Chinese parsley, though it is similar only in appearance to parsley, and cilantro in Southwestern and Mexican cookery. Fresh coriander, which is used as both a flavoring ingredient and a garnish, has an intense smell and imparts a distinctive taste. In the past, it was found only in Asian and Latin American groceries, but it is now widely available. Ideally, you should use it as soon as possible after purchase, so that its bouquet can be appreciated, but it may be refrigerated in a vegetable drawer for up to 1 week.
