Ingredients

1/4 cup extra-virgin olive oil

1 medium onion, chopped

3 garlic cloves, crushed

6 cups water

1 cup dry white wine

2 celery stalks, chopped

1 fennel bulb, chopped

2 whole black bass or sea bass (about 3 pounds each), filleted, head and bones of 1 reserved, flesh cut into 1-inch strips

1 can (28 ounces) whole tomatoes, preferably San Marzano, drained and chopped

5 parsley sprigs

3 thyme sprigs

1 dried bay leaf

1/2 teaspoon whole black peppercorns

1/8 teaspoon saffron threads

5 fingerling potatoes, sliced into 1/4-inch-thick rounds

1 large tomato, seeded and finely chopped

1 teaspoon fresh lemon juice

Coarse salt

12 ounces trofie (twisted pasta)

Flat-leaf parsley sprigs, for garnish

Preparation

Make the broth: Heat oil in a large pot over medium heat. Cook onion and garlic until translucent, about 7 minutes. Add water, wine, celery, fennel, reserved black bass head and bones, canned tomatoes, parsley, thyme, bay leaf, peppercorns, and saffron. Bring to a simmer. Cook, covered, for 45 minutes. Strain through a fine sieve into a clean pot; discard solids.

Make the bouillabaisse: Return broth to a simmer, and add potatoes. Cook until tender, about 10 minutes. Add black bass strips and chopped fresh tomato. Simmer until black bass is cooked through, about 2 minutes. Stir in lemon juice.

Meanwhile, bring a large pot of salted water to a boil. Cook trofie until al dente.

Drain pasta; divide among 6 bowls. Spoon bouillabaisse over pasta. Garnish with parsley.
