As for true endives, two varieties are commonly grown: frisée and escarole. Frisée, also known as "curly endive," has frilly leaves and is often found in salad mixes. Escarole has broad, sturdy, pale yellow to light green leaves that are both bitter and sweet. It makes a great addition to soups or salads. Both greens can be sautéed, grilled, or eaten raw.
