Parmigiano Pumpkin Soup with Frizzled Prosciutto

If your notion of pumpkin is “sweet,” and if you think it should be seasoned only with nutmeg, clove, cinnamon, and sugar, then get ready to change your mind. This savory, creamy, pungently cheesy pumpkin soup is fragrant with garlic and Parmesan, and punctuated with the frizzled threads of crisped prosciutto. Serve it as a first course before a roast (it makes an inspired appetizer for Thanksgiving), or for lunch with someone you’re dying to impress.
