Fresh Shell Bean Soup
As a young man shopping in Boston's North End, a historically Italian neighborhood, chef Peter Pastan would watch customers at his local Italian market ask for the prosciutto skin. He had no idea what they did with it. Today he cures his own meats at his restaurants, then uses prosciutto skin to flavor and thicken soups like this tomatoey fresh shell bean soup. While the skin is optional here, it's easy to obtain—sometimes for free—from delis and meat counters.
