A Roman specialty, crispy curly endive (also known as chicory, and similar to frisee, which can be substituted) is usually served as a side dish to roasts. If you can't find perfect heads of endive, radicchio or even Belgian endive can be used in their place. Because the original recipes don't advise dipping the chicory in a batter or flour, I first tried it unadorned. It was good, but quite greasy. Dripping the greens in an egg wash and flour before frying eliminates the problem.
