(b) Remove both skins of the sole; then, with a sharp-pointed knife, cut it around the inside of the fins. This done, make an incision along the backbone, and divide the fish from the bone by beginning at the head, and drawing the point of the knife horizontally down each side of the backbone, between the flesh and the ribs, and placing at the same time the 3 first fingers of the left hand on the fillet you are about to remove. Each sole should make but 4 fillets, except in the case of very large soles, when they may be either cut lengthways or across, as taste may direct. (Jane Burtenshaw.)
Fricassée.—Fillet a large pair of soles, put the bones in an enamelled stewpan with a pint of cold water, a small bunch of thyme and parsley, and ½ onion, a blade of mace and a little lemon rind pared thin, let them stew about 1 hour; when done strain the liquor off into a basin. Rinse the stewpan, and roll up each fillet separately, and fasten either with a small skewer, or tie round with a piece of darning cotton, and place them in the stewpan in one layer, and pour over them the liquor from the bones; stew about 20 minutes very gently, and thicken the sauce with 1 dessertspoonful arrowroot or cornflour, mixed with a little milk; when done, add to the sauce ¼ pint cream, the yolks of 2 eggs, the juice of ½ lemon, a pinch of pounded mace, and a little pepper and salt. The dish may be garnished with a border of potato croquettes.
Fried.—Clean and skin the fish, and dry it thoroughly in a cloth; dip it in an egg beaten up, and then strew it on both sides with very fine breadcrumbs, taking care that it is evenly covered with a very thin layer of them. Let the fish rest for 1-2 hours, then have ready in the frying-pan boiling hot fat in sufficient quantity to fairly float it; put in the fish, which will be cooked in 5-10 minutes, according to size, and should be skilfully turned over once during the operation. The fish should be laid on blotting-paper before the fire in the screen, in order to drain all fat from it. Serve with fried parsley and cut lemon.
In Brown Sauce.—Put into a small copper stewpan 3 oz. butter. Put this on the fire to dissolve; then stir into it 1 tablespoonful flour. Keep stirring on the fire till it assumes a golden-brown hue. Now stir into it ½ pint stock or gravy, and let it boil up to thicken the sauce. Now put into a wide shallow stewpan a pair of moderate-sized soles that have been previously cleaned, well dried in a cloth, floured and fried in some lard or butter over a rather sharp fire so as to brown them without being quite done. Pour over the soles the prepared sauce, adding a moderate-sized onion stuck with 4 or 5 cloves, a few sprigs of thyme, and a few peppercorns. Stew the fish 15-20 minutes very gently. When the soles are done lift them out carefully on to the dish in which they are to be served and keep warm while the sauce is being finished by adding to it a wineglass of sherry, a tablespoonful of mushroom ketchup, one of vinegar, and two teaspoonfuls of essence of anchovies. Pour some of the sauce over the fish and the rest in a boat and serve.
In Cases.—Take 2 parts finely minced mushrooms, 1 part shallots and parsley in equal proportions, also finely minced; toss them in plenty of butter for a few minutes, adding pepper and salt to taste, and put the mixture aside. When cold spread a thin layer of it on each fillet, roll them up, and cook them between 2 buttered plates in the oven. Have ready some paper cases, place one rolled fillet in each, then fill up the case with white sauce, and place a button mushroom on the top of each, and keep quite hot till time of serving. Sauce.—Take 2 parts butter and 1 of flour, mix thoroughly in a saucepan on the fire, add enough veal stock to get the sauce of a proper consistency, add a few button mushrooms; let the sauce boil for 10 minutes; stir in, off the fire, the yolks of 2 eggs beaten up with the juice of ½ lemon.
Roulettes.—Choose fine ones, take off the heads, fins, and tails, strip them from the bone; cut small oblong fillets, lay them in a marinade of salt, pepper, lemon juice, and a grate of nutmeg for ½ hour. Roll the fillets egg-shaped and bind them with thread; pack them closely together in a stewpan, with a little broth or water, to which add lemon juice and some butter; cover closely and stew gently till done. Serve in their own sauce, or glaze them brown and serve as a ragout.
Salad.—Take any remnants of sole, cut them up in small pieces, and put them to marinade for 2 hours in tarragon vinegar, with some sliced onions and sprigs of basil, thyme, and chervil. Strain and mix them with some fresh lettuce; beat up the yolk of a hard-boiled egg with salt, pepper, a very little of the tarragon vinegar, 3 tablespoons cream or sweet oil, and ½ teaspoon anchovy sauce. When quite smooth pour over the salad.
Savalada.—Take 2 Spanish onions, slice them, and stew them in a gill of olive oil, taking care that they do not burn or even brown; add 2 soles (filleted and fried a light brown in oil), and 1½ gills tomato sauce, or 3 fresh tomatoes, peeled, freed from pips, and cut in slices. Season with pepper and salt, let the whole stew a few minutes, and serve.
Stewed.—Cut up 2 large onions in slices, lay them flat in a stewpan with an ounce of butter, pepper, and salt, and enough water just to cover them. Let them simmer till tender. Cut in comely pieces a pair of soles, lay them on the top of the onions, and let them simmer till done. Strain off the liquor, and when it is cold stir into it the juice of 2 lemons beaten up with the yolks of 3 eggs, return it to the stewpan, and let the whole get hot again, but not boil; then arrange the fish and the onions on a dish, sprinkle them over with finely minced parsley, and pour the sauce over. To be served cold.
Water Souchet.—Take a number of small soles, fillet them, and cut the fillets into convenient pieces. Put the bones and all the trimmings into a saucepan, with some whole pepper, 6 roots of parsley, cut up small, a handful of parsley leaves, a blade of mace, and salt to taste; cover with cold water, and let the whole boil for 2 hours. Strain the liquor, put in it the pieces of fish, with a few parsley roots finely shredded; let it boil 10 minutes, then add some minced parsley; boil 5 minutes longer. Serve in a deep dish, with enough liquor just to cover the fish; garnish with lemon cut in quarters, and serve with brown bread and butter.
