Pare and boil the potato in the quart of water, mash and mix sufficient flour with the water to form a smooth batter. Dissolve the yeast in 1 cup of lukewarm water and combine with the batter. Cover and set in a warm place and let rise for 4 hours. Add the rest of the ingredients and knead, adding flour as needed. Be careful not to get dough too stiff. Let stand for 2 hours, then form into loaves, place in bread pans and let rise until light. Bake at 400-F for 30 to 40 minutes.
