Provençal-Style Fish Soup with Rouille
This is more than a soup; it is a generous meal fit for a gathering, and it has everything I love about food and flavor. I learned to make it from my French “mother,” Lulu. It’s one of the longest recipes in the book, but taken in parts it is not hard to make. I think of it as several steps: first make a fish stock, then prepare the fish and shellfish; make the rouille (garlic mayonnaise flavored with pepper purée); make the soup base with vegetables and the fish stock; toast garlic croutons; and finally put it all together, cooking the fish and shellfish in the deeply flavored soup base, and serve it with rouille and croutons to pass at the table.
