Mince the fish into small pieces, mix with the rice, and add the white sauce. Season with salt and pepper and shape into croquettes. Dip into slightly beaten egg, roll in crumbs, and fry in deep fat. Drain and serve with any desired sauce.

75. CREAMED FISH IN POTATO NEST.--Fish may also be combined with mashed potato to produce a most appetizing dish. Line a baking dish with hot mashed potato, leaving a good-sized hollow in the center. Into this pour creamed fish made by mixing equal proportions of left-over cold fish and white sauce. Season well with salt and pepper, sprinkle with crumbs, and dot the top with butter. Bake until the crumbs are brown. Serve hot.

SHELL FISH

NATURE, VARIETIES, AND USE OF SHELL FISH

76. Besides the varieties of fish that have already been considered, the general term fish also includes SHELL FISH. Fish of this kind are different in structure from bony fish, for they are acquatic animals that are entirely or partly encased in shells. They include mollusks, or bivalves, such as oysters, clams, and scallops, and crustaceans, such as lobsters, crabs, and shrimp.

77. The popularity of the edible varieties of mollusks and crustaceans mentioned depends largely on whether they can be easily obtained and whether they are pleasing to the local or individual taste. As they are found in salt rivers, bays, and other shallow salt-water sources, their greatest use is among people living near the seashore, but they are much favored where they can be procured in edible condition. They are not so cheap as many other fish foods; that is, a certain amount of money will not purchase so great a quantity of shell fish, lobster for instance, as some of the well-known varieties of fish proper, such as halibut or whitefish. Lobsters and crabs are usually more expensive than oysters and clams; consequently, they are used more often to provide a delicacy or to supply something more or less uncommon for a special meal.
