A mild-flavored member of the parsley family, this aromatic herb has curly, dark green leaves with an elusive anise flavor. Though most chervil is cultivated for its leaves alone, the root is edible and was, in fact, enjoyed by early Greeks and Romans. Today it is available dried but has the best flavor when fresh. Both forms can be found in most supermarkets. It can be used like parsley but its delicate flavor can be diminished when boiled.
