A member of the chicory family, frisée has delicately slender, curly leaves that range in color from yellow-white to yellow-green. This feathery vegetable has a mildly bitter flavor and is often used in the special salad mix, mesclun. Choose frisée with crisp leaves and no sign of wilting. Refrigerate in a plastic bag for up to 5 days. Wash just before using.
