To Cook Fish in Boiling Water. Small cod, haddock, or cusk are cooked whole in enough boiling water to cover, to which is added salt and lemon juice or vinegar. Salt gives flavor; lemon juice or vinegar keeps the flesh white. A long fish-kettle containing a rack on which to place fish is useful but rather expensive. In place of fish-kettle, if the fish is not too large to be coiled in it, a frying-basket may be used placed in any kettle.
Pieces cut from large fish for boiling should be cleaned and tied in a piece of cheese cloth to prevent scum being deposited on the fish. If skin is not removed before serving, scald the dark skin and scrape to remove coloring: this may be easily accomplished by holding fish on two forks, and lowering into boiling water the part covered with black skin; then remove and scrape. Time required for boiling fish depends on extent of surface exposed to water. Consult Time Table for Boiling, which will serve as a guide. The fish is cooked when flesh leaves the bone, no matter how long the time.
To Broil Fish. Cod, haddock, bluefish, and mackerel are split down the back and broiled whole, removing head and tail or not, as desired. Salmon, chicken halibut, and swordfish are cut in inch slices for broiling. Smelts and other small fish are broiled whole, without splitting. Clean and wipe fish as dry as possible, sprinkle with salt and pepper, and place in well greased wire broiler. Slices of fish should be turned often while broiling; whole fish should be first broiled on flesh side, then turned and broiled on skin side just long enough to make skin brown and crisp.
To Bake Fish. Clean, and bake on a greased fish-sheet placed in a dripping-pan. If a fish-sheet is not at hand, place strips of cotton cloth under fish, by which it may he lifted from pan.
To Fry Fish. Clean fish and wipe as dry as possible. Sprinkle with salt, dip in flour or crumbs, egg, and crumbs, and fry in deep fat.
To Sauté Fish. Prepare as for frying, and cook in frying-pan with small amount of fat; or, if preferred, dip in granulated corn meal. Cod steak and smelts are often cooked in this way.
