Scapes are the flower stalks found on all members of the Allium family (onions, leeks, chives, and garlic). Garlic scapes are a delicacy in some Asian cuisines and are available occasionally at farmer's markets as well as gourmet restaurants.
Garlic scapes have a pleasant, subtle garlic taste and can be treated as a replacement for green onions, garlic, chives, or shallots in recipes you cook every day. Eat them raw or cooked. Just slice the beautiful curves (flower tops and all) into long wands or thin rounds and add them to a dish—just at the end, if you are cooking them. . Too much cooking destroys the fresh flavor. Your scapes will store in the refrigerator for a couple of weeks.
Scapes are also wonderful in a garlic scape pesto—look for the recipe on this site
