3 1/2 c. flour (approximately)
2 c. whole wheat flour
1 c. rye flour
2 c. cornmeal
2 c. cracked wheat
1/2 c. non-fat dry milk
4 tsp. salt
1 pkg. dry yeast, dissolved in 1 pt. warmed chicken stock or other liquid
1 egg, mixed with 1 tbsp. milk to brush on top of each biscuit

Mix the ingredients together. Knead about 3 minutes, working it into a stiff dough. Roll the dough into 1/4 inch sheet and cut out in any shape. Brush the biscuits with the egg and milk mixture or it could also be added into the mixture. Bake at 300 degrees for 45 minutes; turn the heat off and leave the biscuits in the oven overnight. They should be hard and dry. (My kids liked them just as well as the dog!)
