Fillets of Halibut, with Potatoes.
3 lbs. of halibut, cut into strips three inches long, one wide, and three-quarters of an inch thick; 3 tablespoonfuls of butter; pepper; salt; 1 teaspoonful of anchovy paste; a pinch of cayenne; a little boiling water; juice of a lemon.
Lay the slices of fish in salt and water for half an hour. Wipe them dry. Have ready the butter in a saucepan, with pepper and salt. When it is hot, put in the pieces of fish, and cook gently, without browning, until tender.
Meanwhile, cut some potatoes round with your “gouge,” or, if you have none, into neat squares; parboil and drain them, and simmer ten minutes in enough hot milk to cover them; then stir in a lump of butter; season with pepper and salt. Cook five minutes; drain the liquid into another saucepan, and keep the potatoes hot. Lay the fish in order upon a hot dish, the potatoes around it, and set over hot water, while you thicken the milk in which the potatoes were boiled (never omitting the pinch of soda), with a little flour. Boil up, add the butter used for cooking the fish, and the anchovy sauce. Squeeze a small lemon over the fish, and pour on the hot sauce.
