Caldeirada à fragateira
The fragateiros sailed the flat-bottomed barges that carried cargo up and down the Tagus, and on board they cooked whatever fish they had in one pot, layered with potatoes, onions, tomatoes and peppers and left to steam in olive oil and wine. Lisbon restaurants still make caldeirada for a long lunch, ladled over toasted bread. Use at least three kinds of fish, mixing firm white ones with something richer. The wine contains alcohol; fish stock with a squeeze of lemon makes a good alcohol-free version. A common mistake is stirring the pot, which breaks the fish; shake it instead. Chef's tip: put the firmest fish at the bottom and the most delicate on top, so everything is done at the same time.
