In a small bowl, dissolve yeast in warm water. In a large bowl, combine beef broth, milk, honey, egg, bacon grease or margarine, and salt. Add yeast/water mixture and mix well. Stir in flour, corn meal, wheat germ, cracked wheat, wheat bran, oatmeal, and cheese. Add whole wheat flour, 1/2 cup at a time, mixing well after each addition. Knead in the final amounts of flour by hand to make a stiff dough. Continue to knead for 4 to 5 minutes. Pat or roll to 1/2 inch thickness. Cut into bone shapes and place on a greased baking sheet. Cover lightly and let set (rise) for 30 minutes. Bake in a 350û oven for 45 minutes or until lightly browned on bottom. Prepare topping during last few minutes. Turn off oven heat. Remove biscuits from oven. Immediately dip biscuits in topping. Return them to oven and leave biscuits in oven for several hours or overnight.
