bouillabaisse

Bouillabaisse ( , , ; ) is a traditional Provençal fish soup originating in the port city of Marseille. The word is originally a compound of the two Provençal verbs ('to boil') and ('to reduce heat', i.e. 'simmer').

Bouillabaisse was originally a dish made by Marseille fishermen, using bony rockfish, which they were unable to sell to restaurants or markets. There are at least three kinds of fish in a traditional bouillabaisse: typically red rascasse (Scorpaena scrofa); sea robin; and European conger. It can also include gilt-head bream, turbot, monkfish, mullet, or European hake. It usually also includes shellfish and other seafood such as sea urchins, mussels, velvet crabs, spider crabs, or octopus. More expensive versions may add langoustine (Dublin Bay prawn; Norway lobster), though this was not part of the traditional dish made by Marseille fishermen. Vegetables such as leeks, onions, tomatoes, celery, and potatoes are simmered together with the broth and served with the fish. The broth is traditionally served with rouille, a mayonnaise made of olive oil, garlic, saffron, and cayenne pepper, on grilled slices of bread.
