Put the mackerel into a large pan of cold water with the skin up, and soak it all one afternoon and night, changing the water four times. In the morning put it in a pan on the fire with enough water to cover it, and drop in a slice of onion, minced fine, a teaspoonful of vinegar, and a sprig of parsley. Simmer it twenty minutes,--that is, let it just bubble slowly,--and while it is cooking make a cup of white sauce as before: one tablespoonful of butter, melted, one tablespoonful of flour, one cup of hot milk, a little salt. Cook till smooth. Take up the fish and pour off all the water; place it on a hot platter and pour the sauce over it.
The mackerel is one of the most beautiful of fish, being known by its silvery whiteness. It sometimes attains to the length of twenty inches, but usually, when fully grown, is about fourteen or sixteen inches long, and about two pounds in weight. To carve a baked mackerel, first remove the head and tail by cutting downward at 1 and 2; then split them down the back, so as to serve each person a part of each side piece. The roe should be divided in small pieces and served with each piece of fish. Other whole fish may be carved in the same manner. The fish is laid upon a little sauce or folded napkin, on a hot dish, and garnished with parsley.
Put the fish into cold water with a handful of salt, and let it slowly and gradually warm for three hours if the cod is large, and two hours if it is small. Then increase the fire, and boil it hard for a few minutes only.
Choose small fish of different kinds and fillet them. As only half the fillets are wanted for the souchet, the rest may be dressed in another way. Wash the bones in cold water and remove the black substance from them, put them into two quarts of cold water with a teaspoonful of salt, and when it boils remove the scum and add 1 dozen peppercorns, one carrot, one small turnip, one onion, a small piece of celery, and a fagot of herbs. Put the vegetables in whole. Boil this together for one hour, then strain off through a hair sieve and return to the saucepan; wash the vegetables that have been boiled in it, slice them up and put them into the liquor. Cut the fillets of fish into small pieces and put them in; simmer for half an hour, then put in a little lemon juice, pour into a tureen, and sprinkle a little chopped parsley on the top. Send brown bread and butter to table with it and a lemon.
Soak herring a few hours, when washed and cleaned, bone and chop. To one herring take one onion, one sour apple, a slice of white bread which has been soaked in vinegar, chop all these; add one teaspoon oil, a little cinnamon and pepper. Put on platter in shape of a herring with head at top and tail at bottom of dish, and sprinkle the chopped white of a hard-boiled egg over fish and then the chopped yolk.
Select a large, fine fish, clean it thoroughly, put it over the fire with a sufficient quantity of water, allowing for each pound of fish one quart of water; add an onion cut fine and a bunch of sweet herbs. When the fish is cooked, and is quite tasteless, strain all through a colander, return to the fire, add some butter, salt and pepper to taste. A small tablespoonful of Worcestershire sauce may be added if liked. Serve with small squares of fried bread and thin slices of lemon.
Half a cupful of melted butter, half a cupful of vinegar, two tablespoonfuls of tomato catsup, salt, and a tablespoonful of made mustard. Boil ten minutes.
Wash the roots and scrape off their skins, throwing them, as you do so, into cold water, for exposure to the air causes them to immediately turn dark. Then cut crosswise into little thin slices; throw into fresh water, enough to cover; add a little salt and stew in a covered vessel until tender, or about one hour. Pour off a little of the water, add a small lump of butter, a little pepper, and a gill of sweet cream and a teaspoonful of flour stirred to a paste. Boil up and serve hot. Salsify may be simply boiled and melted butter turned over them.
