Chilled Garlic and Spinach Soup
Green garlic, which greatly resembles an overgrown scallion, has a mild flavor. Heads of fresh garlic are mature but just harvested. Because they haven't been cured for winter storage, they're very juicy. If you can't find either type of garlic, substitute scallions for the green garlic and regular (cured) garlic for the fresh. The soup will still be delicious.
