When the broth is where you want it to be, strain it to remove the shells. Then, add nicely diced potatoes, medium-diced carrots and celery, and the corn, (for color and round out the soup). As a final step, add a beautiful piece of fish, lobster or shrimp to the soup and allow to gently cook just until perfectly opaque. Right before serving, add a drizzle of heavy cream and another splash of sherry, if you like.
