String and remove the ends from one quart of beans. Cut into short lengths. Cover with boiling water, add one level tablespoon of wilt and cook until tender, but not soft. Drain and save one cup of the liquor. Cream one tablespoon of flour with two tablespoons of butter. Pour the liquid over the flour and butter, stirring constantly to avoid “lumping.” Cook this sauce for five minutes, remove from stove and stir in two tablespoons of strained lemon juice. Pour this over the beans and serve.
