Yassa Fish and Shrimp
Poisson yassa is the fish version of Senegal's best known dish, and it works on the same principle as chicken yassa: a marinade of lemon, mustard, garlic and onion that becomes the sauce, with a very large quantity of onion cooked down into it. Yassa comes from the Casamance region in southern Senegal and is now made across the country and throughout the Senegalese diaspora. The mustard is a French ingredient absorbed entirely into a Senegalese idiom, and the resemblance the source draws to a French sauce à l'onion is fair as far as it goes, though yassa is sharper and carries far more onion. Four large onions to two and a half pounds of fish is the ratio, and it is not a mistake. The onions cook down into a soft, tangy mass that is as much the dish as the fish is. The technique is straightforward: marinate, cook the fish and set it aside, cook the onions in the leftover marinade, then return the fish to warm through in the sauce. Shrimp can go in alongside. It is served with rice most often, though this version suggests potatoes.
