BAKED HALIBUT

Soak six pounds of halibut in salt water for two hours. Wipe dry and score the outer skin. Bake for an hour in a moderately hot oven, basting with melted butter and hot water. Add a little boiling water to the gravy, a tablespoonful of walnut catsup, a teaspoonful of Worcestershire sauce, salt and pepper to season, and the juice of a lemon. Cook while stirring with browned flour rubbed smooth with a little cold water.
