Mushrooms, Sauce of, Brown

Button or flap mushrooms may be used for this sauce. They should be rinsed in cold water, drained, and dried in a soft cloth, and, if flap ones, cut into pieces. Simmer the mushrooms, without stalks, in half a pint of beef gravy, add a little mushroom ketchup, and an ounce of butter, blended with flour. If liked, flavour with lemon-peel, and squeeze in some of the juice before serving. Time, twenty to twenty-five minutes.
