Fish is so versatile that it can be simmered in almost any liquid to make a great soup. Every culture seems to have thought of cooking fish in a pot with some liquid and local vegetables, herbs, and spices, in infinite variety.
Fish soups are much appreciated in Asia and Europe, where they are served at different stages in a meal or as meals in themselves. Americans, who used to think of fish as a cheap substitute for meat, are now eating it more because it’s light and nutritious. Now that better, fresher, and more varied fish is appearing in markets, Americans are sampling fish dishes they didn’t even know existed a decade ago.
