Wash one pound of prunes or plums and put on to boil with one pound of brisket of beef or any fat meat; when the meat is tender add five medium-sized sweet potatoes which have been pared and cut in small pieces. Place the meat on top, add one-half cup of sugar and a piece of sour salt (citric acid). Cover and bake until nicely browned. If gravy should cook away add some warm water.
