If a tasty as well as a slightly unusual dish is desired to give variety to the diet, baked scallops will undoubtedly find favor. As shown in the accompanying recipe, mushrooms are one of the ingredients in baked scallops and these not only provide additional material, but improve the flavor.
To prepare baked scallops, clean the desired number, parboil for 15 minutes, drain, and cut into small pieces. For each cupful of scallops, melt 2 tablespoonfuls of butter in a frying pan, sauté in it 1 tablespoonful of chopped onion, and add 1/2 cupful of chopped mushrooms. When these have browned, add 2 tablespoonfuls of flour and 1 cupful of milk. Cook until thick and then add the scallops. Fill the scallop shells with the mixture, sprinkle with buttered bread crumbs, place in the oven, and bake until the crumbs are brown.
