This very American fish chowder has a rich flavor without a cream base. The small amount of cream that is added at the end is there to "finish" the soup, to enrich and smooth it. This chowder is not about cream; it's about fresh salmon, corn and potatoes, and bacon. Serve it as a warming main dish, in bowls or in cups, followed by a crisp, clean-tasting salad. The flavors are fullest if you serve right after adding the cream.
