To brown flour for gravy, put it in a pan when baking and brown it in the oven. It may be kept in a jar ready for use.
Use two tablespoonfuls of flour and one teaspoonful of butter for each cupful of milk. Smooth the flour into part of the milk to make a paste. Let part of the milk get to boiling point, dip out a little and stir in with the cold paste, then stir the paste quickly into the hot milk. Add butter, season with salt and remove from fire as soon as the mixture thickens.
