Lettuce Frisse

Is a variation of endive, also referred to as curly endive. This endive has an open head with curly, strongly shaped leaves. The heart of the lettuce is yellow with the outer leaves green, which  can be cooked, but are more often used raw in salads. The tender inner leaves are best suited to eating fresh, while the outer leaves can become tough. Cooking these outer leaves can soften the texture and flavor, but they can quickly be overcooked. Frisée tastes slightly bitter and peppery. Many people use it sparingly in salads rather than as the main ingredient.
