Fennel grows like a weed - and literally as a roadside weed - all over Europe. A celery-like thing, with a cool licorice flavor. You can munch on it raw, sautee it, or pickle it either as refrigerator pickles or real pickles. Fenuil in French, finocchio in Sicily and Italy.
It's perfect with simple seafood. Here's my first course (lousy photo): Warm salad of sliced octopus on a bed of sauteed fennel.
Main course (which was not really needed) - a rare filet of French beef with a jus with olives, not mushrooms. And usual Euroland runny mashed taters.
