Brown Sauce

Brown the butter slightly, add the flour and stir constantly until the flour is a rich brown. Add the seasoning and stock, one-third at a time, stirring it until smooth. If butter is not used, add the flour as soon as the fat is melted, as other fats will acquire a strong flavour if allowed to brown before the flour is added. Mutton or lamb fat, or that from smoked or salted meats, is not suitable for brown sauce.
