Peel potato and slice thin. Add potato to the boiling water to which the 1 tablespoon sugar, meal and 1 tablespoon salt have been added. Keep this mixing warm overnight or until ferments and smells. Take out the slices of potato and add the cup of scalded milk and enough flour to make a stiff batter. Keep warm until it rises. Then add the warm water, shortening, 1 teaspoon salt and enough flour to make consistency of bread dough. Put in greased pan and let rise. Bake at 350 degrees for 45 minutes.
