227. Mackerel au Beurre Noir.—Split the mackerel open at the back, making it quite flat, season with a little pepper and salt, and butter it all over, lay it upon a gridiron over a moderate fire, turning it when half done, for about a quarter of an hour, when place it upon a dish without a napkin, then put six ounces of fresh butter in a stewpan, which place over a sharp fire until the butter becomes black, but not burnt, when throw in about fifty leaves of picked parsley, which fry crisp, and pour over the fish, put three tablespoonfuls of common vinegar into the stewpan, which boil half a minute, season with pepper and salt, pour this also over the fish, which put into the oven five minutes, and serve very hot.
228. To stew Mackerel.—Take off the heads, the fins, and tails, and, having opened the fish and taken out all the hard roes, dry them with a cloth and dredge them lightly with flour; place three or four of them in a stewpan, with a lump of butter, the size of a walnut, to each fish; put into a small basin a teacupful of water, a tablespoonful of finely-chopped onions, the same of chopped parsley, a blade or two of mace, a little pepper and salt, a tablespoonful of anchovy essence, and a small teacupful of ale or porter (if not bitter). Add a tablespoonful of grated bread-crust, not burnt, but a light brown; pour all these ingredients over the fish, and let them stew gently for twenty minutes; have ready the yolks of three eggs, well-beaten, and when the fish is sufficiently done, take some of the gravy and mix gradually with the eggs, and, pouring them on the fish, shake the stewpan a little over the fire to thicken the whole, but not to curdle the eggs; the soft roes added are an improvement: have ready more grated crust, and having placed the fish whole in the dish, shake a little of the grated crust over the whole, so as to make it of a handsome brown. The Receipt requires to be carefully followed. If the gravy is too thick, more water may be added; also a glass of sherry, if liked.
229. Fried Whiting.—The whiting is generally skinned, and the tail turned round and fixed into the mouth; dip it first into flour, then egg over and dip it into bread-crumbs, fry as directed for the sole; for whiting aux fines herbes, proceed as directed for sole aux fines herbes. I prefer the whiting fried with their skins on, merely dipping them in flour.
230. Whiting au Gratin.—Put a good spoonful of chopped onions upon a strong earthen dish, with a glass of wine, season the whiting with a little pepper and salt, put it in the dish, sprinkle some chopped parsley and chopped mushrooms over, and pour over half a pint of anchovy sauce, over which sprinkle some brown bread-crumbs, grated from the crust of bread, place it in a warm oven half an hour; it requires to be nicely browned; serve upon the dish you have cooked it in.
231. Red Mullets.—Procure two red mullets, which place upon a strong dish, not too large, sprinkle a little chopped onions, parsley, a little pepper and salt, and a little salad-oil over, and put them into a warm oven for half an hour, then put half a tablespoonful of chopped onions in a stewpan, with a teaspoonful of salad-oil, stir over a moderate fire until getting rather yellowish, then add a tablespoonful of sherry, half a pint of white sauce or melted butter, with a little chopped parsley; reduce over a sharp fire, keeping it stirred until becoming rather thick; when the mullets are done, sauce over and serve.
