MELTED BUTTER — another way

Put into a sauce-pan a quarter of a pound of butter. When quite melted over the fire, throw in a large spoonful of flour, and add a half pint of boiling water, and salt to your taste. Boil it a few minutes, and then put in a tea-spoonful of cold water. If intended as sauce for a pudding, stir in at the last a glass of white wine, and half a grated nutmeg.
