Take six good-sized potatoes; cook until very soft; take from the water, and mash until creamy; turn the water over the potato scalding hot, and stir in flour until the consistency of cake batter. When cool, stir in one cup of good yeast dissolved in a little warm water; let rise over night. First thing in the morning, heat two quarts of water milk warm; add to the yeast; then stir in flour to make a thick sponge; let rise; then work to a stiff dough; let rise again; knead down; let rise again; make into loaves. When light, bake from three quarters to one hour. This makes a large baking.
