Flake salmon. Remove bones. Combine salmon, potatoes, beans, onions, and melted butter. Season to taste. Mix until well blended. Fold in stiffly beaten egg whites. Pour into well-oiled baking dish. Bake in moderate oven (400 F) until puffy and brown. Serve at once with sour pickles and tartare or tomato sauce. Mrs. Zola Simonsen, Emery, UT in The Household Searchlight Recipe Book (1934)
