Instructions
Making the stock
Cook the onions and leeks slowly in olive oil for 5 minutes or until almost tender but not browned.
300 ml onions, 200 ml leek, 150 cup olive oil
Stir in the garlic and tomatoes. Raise heat to moderate and cook 5 minutes more.
4 clove garlic, 500 g tomatoes
Add the water, herbs, seasonings, and fish heads, bones, and trimmings to the kettle (or clam juice) and cook uncovered at a moderate boil for 30 to 40 minutes.
2.5 lt water, 6 parsley springs, 1 bay leaf, 1/2 tsp thyme or basil, 1/2 tsp fennel, 2 big pinches of saffron, orange peel, 1/2 tsp pepper, 2 to 3 kg fish scraps, 1 tbsp salt
Strain the soup into the saucepan, pressing juices out of ingredients. Correct seasoning, adding a bit more saffron if you feel it necessary.
You should have 2 1/2 quarts of in a higher, rather narrow kettle.
Cooking the seafood and assembly
Bring the soup to a rapid boil 20 minutes before serving. Add lobsters, crabs, and firm-fleshed fish. Bring quickly back to the boil and boil rapidly for 5 minutes. Add the tender-fleshed fish, the clams, mussels, and scallops. Bring rapidly to the boil again and boil 5 minutes more or until the fish are just tender when pierced with a fork. Do not overcook.
3 to 4 kg fish
Immediately lift out the fish and arrange on the platter. Correct seasoning, and pour the soup into the tureen over rounds of French bread. Spoon a ladleful of soup over the fish, and sprinkle parsley over both fish and soup. Serve immediately accompanied by the optional rouille.
Notes
To prepare the fish for cooking, have them cleaned and scaled. Discard the gills. Save heads and trimmings for fish stock. Cut large fish into crosswise slices 2 inches wide. Scrub clams. Scrub and soak the mussels. Wash scallops. If using live crab or lobster, split them just before cooking. remove the sand sack and intestinal tube from lobsters.
