Chef Van Aken writes: "I have made a version of this soup for over 20 years now and I never tire of it. It’s one of those soups that actually can be a full lunch or dinner. As with many soups, this improves if made a day ahead of time, which makes it an ideal party dish. I like to keep it traditional and offer a shot of dry sherry at the table. It really rounds out the flavors. Serve with warm bread and butter in that the soup is a touch spicy."
