Mix all ingredients well, adding bread flour last until dough is a good texture and not sticky. (In bread mixer, add until the dough begins to clean the sides of the bowl.) Knead the dough for 10 minutes. Put into a large greased bowl and let rise in a warm place for one hour. Grease five loaf pans. Divide the dough evenly into five pieces. It helps to weigh the loaves with a kitchen scale. Shape into loaves, place into the greased pans and spray the tops with cooking spray. Cover the pans and let rise for another hour or until a small depression in the dough stays when you poke it. Bake at 350°F for 30-35 minutes. If your oven is small, it's good to turn the pans about halfway through to keep the heat evenly distributed.
