Put one chopped onion and one very finely chopped green pepper - the seed extracted - in a stewpan; brown them in a half gill of oil for five minutes, then add one tomato, cut in pieces, four sliced mushrooms, a good bouquet (No. 106), and a clove of garlic. Season well with a pinch of salt and half a pinch of pepper, then moisten with half a pint of Espagnole sauce (No. 110). Cut a fish weighing three pounds in six slices, lay them flat in the stewpan, with three table-spoonfuls of mushroom liquor (if any handy), and let cook for one hour on a very slow fire. When ready to serve, sprinkle over with a pinch of chopped parsley, and decorate with six pieces of heart-shaped crouton (No. 116). (All fish a la Creole are prepared the same way, the time allowed for cooking depending on the firmness of the fish. The fish can be left whole instead of dividing in slices, if desired.)
