Soak the mackerel for twelve hours or more, with the skin side up, and change the water several times. Simmer it for fifteen or twenty minutes; and, if convenient, have in the water one teaspoonful of vinegar, one bay-leaf, one slice of onion, and a sprig of parsley. When tender, place carefully on a hot dish, and pour over it a cream sauce; or the soaked fish may be broiled, and spread with butter, pepper, lemon juice, and chopped parsley.
Soak the mackerel for twenty-four hours, then lay it in a shallow stew-pan, and cover with milk or cream. Simmer for fifteen minutes. Remove the fish carefully, and place it on a hot dish. Add to the milk or cream in the stew-pan one tablespoonful each of butter and flour rubbed together. Stir until a little thickened, and the flour cooked; add a little pepper and chopped parsley, and pour the sauce over the fish.
Soak the codfish several hours, changing the water three times. Simmer it for 20 minutes or until it is tender. Take out carefully all the bones. Make a white sauce of one tablespoonful each of butter and flour, and one cupful of milk; add to it, off the fire, two beaten yolks. Return to the fire, and stir in one cupful of shredded codfish. Taste to see if it needs seasoning with salt and pepper. Serve it on slices of toast, or place it in center of dish, and surround it with triangular croutons.
Boil the quantity of codfish that will be needed, changing the water once, that it may not be too salt. While the fish is hot, pick it very fine, so that it is feathery; it cannot be done fine enough with a fork, and should be picked by hand. At the same time have hot boiled potatoes ready. Mash them thoroughly, and make them creamy with milk and a good-sized lump of butter. To three cupfuls of the mashed potatoes take one and one half cupfuls of fish. The fish should not be packed down. Beat one egg lightly, and stir into the other ingredients; season to taste. Beat the mixture well together and until light, then mold it into small balls, handling lightly, and before frying, roll the balls in flour. Fry them in smoking hot fat until a golden color*
Drain sardines from the can. Lay them on a broiler over hot coals for two minutes on each side. Have ready hot toast cut the right size to hold three of the fish. Arrange them neatly on the toast, and moisten with a little heated oil from the can.
To one cupful of flaked boiled fish add a cream sauce made of one tablespoonful of butter, one tablespoonful of flour, and one half cupful of milk.
Let the sauce be very stiff, so it leaves the sides of the pan; mix it well with the fish, and when hot add two beaten eggs, pepper, and salt. Drop the mixture, which should be like thick batter, from a spoon into very hot fat.
It will puff, and be very light.
