Split the fish, remove all bones, season with fine salt, cayenne and drops of lemon juice. Mix together 2 cups cracker meal and 1 cup grated or finely minced cheese (any kind.) Dip the sides of the fish in beaten egg in a shallow pan, then in the cracker dust mixture ana let lie in it awhile. Spread a baking pan with soft butter, lay the fish in and bake slowly, basting once with melted butter. The pan should be roomy that the pieces of fish may not be crowded together. Serve hot and crisp without sauce, but with potatoes in the same plate.
