Fleshy outer escarole leaves, too tough for salad, make a delicious "what-is-this?" side dish. Slowly wilted, the sturdy leaves fall into gorgeous, satiny folds with a long, earthy, sweet flavor. Don't be tempted to use the pale escarole hearts—they usually turn brown and lack sweetness; save them for salads. Good with fish, poultry, pork, or beef.
