Bouillabaisse with Spicy Rouille

Heat oil in a Dutch oven over medium-high heat. Add leeks, celery, garlic and fennel seed and cook, stirring often, until the leeks are softened, 3 to 4 minutes. Add tomatoes and potatoes; cook, stirring often, until the tomatoes begin to break down, about 4 minutes. Add wine, increase heat to high, bring to a boil, and cook, stirring often, until reduced, 2 to 3 minutes. Add clam juice, water, orange peel, bay leaves and saffron and bring to a boil. Reduce heat and simmer, stirring occasionally, until the potatoes are just tender, about 15 minutes.

Carefully submerge tilapia and scallops in the soup, return to a simmer and cook for 2 minutes. Add calamari, submerge in the soup, and continue cooking until cooked through, about 3 minutes. Discard orange peel and bay leaves. Serve the soup with a spoonful of Spicy Rouille on top.
