Also known as Italian cress, rocket, roquette, rugula and rucola, arugula is a bitterish, aromatic salad green with a peppery mustard flavor. Though it has long been extremely popular with Italians, American palates often find its flavor too assertive. Arugula (which resembles radish leaves) can be found in specialty produce markets and in most supermarkets. It's sold in small bunches with roots attached. The leaves should be bright green and fresh looking. Arugula is very perishable and should be tightly wrapped in a plastic bag and refrigerated for no more than two days. Its leaves hold a tremendous amount of grit and must be thoroughly washed just before using. Arugula makes a lively addition to salads, soups and sautéed vegetable dishes. It's a rich source of iron as well as vitamins A and C.
