Peel a marrow and cut it in half length-ways. Prepare some veal forcemeat by recipe given elsewhere, and make it hot in a saucepan. Remove the seeds from the marrow and put in their place the forcemeat; put the pieces together and bind round with tape. Have ready a fish kettle full of boiling water seasoned with salt; lay the marrow on the drainer and plunge into the water; boil gently for about twenty-five minutes. Slip the marrow carefully into a dish and pour over some melted butter sauce.
Make the veal seasoning by recipe given elsewhere; sew it into the eel and put it into a deep dish. Just cover it with water, and bake it in a good oven for about one hour. Take it up and keep hot, strain the liquor in which it has been cooked; take about one pint and make into a brown sauce with the butter and flour. Colour it with a few drops of caramel, let it boil for a few minutes, season with salt, pepper, and lemon juice; pour over the fish, and serve very hot.
Soak salmon in tepid or cold water twenty-four hours, changing water several times, or let stand under faucet of running water. If in a hurry, or desiring a very salt relish, it may do to soak a short time, having water warm, and changing, parboiling slightly. At the hour wanted, broil sharply. Season to suit taste, covering with butter. This recipe will answer for all kinds of salt fish.
Combine ingredients as directed in the recipe, roll the mixture lightly between the hands into a ball. Have a plentiful supply of bread crumbs spread evenly on a board; roll the ball lightly on the crumbs into the shape of a cylinder, and flatten each end by dropping it lightly on the board; put it in the egg (to each egg add one tablespoon of water, and beat together), and with a spoon moisten the croquette completely with the egg; lift it out on a knife-blade, and again roll lightly in the crumbs. Have every part entirely covered, so there will be no opening through which the grease may be absorbed. Where a light yellow color is wanted, use fresh white crumbs grated from the loaf (or rubbed through a purée sieve) for the outside, and do not use the yolk of the egg. Coarse fresh crumbs are used for fish croquettes, which are usually made in the form of chops, or half heart shape. A small hole is pricked in the pointed end after frying, and a sprig of parsley inserted. Have all the croquettes of perfectly uniform size and shape, and lay them aside on a dish, not touching one another, for an hour or more before frying. This will make the crust more firm. The white of an egg alone may be used for egging them, but not the yolk alone. Whip the egg with the water, just enough to break it, as air-bubbles in the egg will break in frying, and let the grease penetrate. Serve the croquettes on a platter, spread them on a napkin and garnish with sprigs of parsley.
