In saucepan, mix water, milk, bacon fat and molasses. Heat to lukewarm. Sift 4 cups flour, sugar and salt together. Sprinkle yeast over this. Add the lukewarm mixture and beat with a mixer until smooth. Gradually add enough of remaining 5 cups flour, to form a stiff dough. Knead on a floured surface until dough is no longer sticky. Put the dough in a greased bowl, and place in a warm place until it has doubled in bulk. Punch down, knead, and shape into 4 loaves. Place in greased loaf pans and let rise again until double in bulk, about 1 to 1- half hour. Cover and bake at 160ºC or 1 hour. Remove from oven. Brush tops with melted multer and allow to stand for 5 minutes. Remove from pans and cool on wire racks.
