Asparagus Soup with Parmigiano Zabaglione
Chef's Notes: The keys to achieving a brilliant green color for this soup are blending the barely cooked asparagus with fresh spinach leaves, adding a bit of vitamin C for its antioxidant effects, and cooling the soup as quickly as possible. You can make both the soup and the zabaglione the day before serving them. Add the whipped cream to the zabaglione up to 8 hours ahead, but no longer, or it will deflate and not float as beautifully on top.
