Hake, which is not one of the most delicate fish, can be made excellent if stewed in the following sauce: A quart of milk to which you have added a dessertspoonful of any of the good English sauces; thicken it with a knob of butter rolled in flour, which stir in till all is smooth. When it boils take off the fire, and put in your pieces of hake, set it back by the side of the fire to keep very hot, without boiling, for twenty-five minutes. Meanwhile mash some potatoes, and put it as a purée round a dish, pour the fish in the center, sprinkle on it chopped parsley. The liquor ought to be much reduced.
VERY NICE SKATE
Take skate, or indeed any fish that rolls up easily, make into fillets, dry them well, and sprinkle on each fillet, pepper, salt, a dust of mixed spice, and chopped parsley. Roll each fillet up tightly, and pack them tightly into a dish, so that they will not become loose. Take vinegar and beer in equal quantities, or, if you do not like to use beer, you must add to the vinegar some whole black pepper, and a good sprinkle of dried and mixed herbs with salt. Pour over the fish, tie a piece of buttered paper over the top, and bake for an hour and a quarter (for a medium pie dish) in a moderate oven.
TO KEEP SPRATS
A large quantity of these may be bought cheaply and kept for some weeks by this method. Put on to warm equal quantities of vinegar and water, what you think sufficient to cover your sprats, allowing for wastage; and stir in for every quart of liquor a small saltspoonful of mixed spice, four bay leaves, a shallot minced, a small bunch of bruised thyme, the thin rind of a half lemon, salt and pepper; if you can use tarragon vinegar so much the better. Clean the sprats, remove tails and heads, and lay them in a deep dish. Take your liquor and pour it over the fish, tie a large paper over all, and let them bake in a cool oven for two or three hours; or cook them in a double saucepan; in any case do them very slowly. Put aside to cool, and take out the fish to use as required. They will keep good four weeks.
