Mix the all-purpose flour, rye flour, corn meal, powdered milk, cracked wheat and salt in a large mixing bowl.
Step 2:
Put the warm water in a bowl and sprinkle the active dry yeast over the water. Stir it until the yeast dissolves.
Step 3:
Add the chicken broth and the softened yeast to the bowl of dry ingredients, and mix it well. Use your hands, because the dough will be stiff. Add a bit more chicken broth or water is the dough is too dry.
Step 4:
Roll the dough to about ¼-inch thickness on a lightly floured surface, and cut it into biscuits with a biscuit cutter or cookie cutters.
Step 5:
Mix beaten egg with a small amount of milk. Put the biscuits on ungreased baking sheets and brush them with the egg and milk mixture.
Step 6:
Bake the people and dog biscuits at 300 degrees for 45 minutes.
Step 7:
Turn off the oven, but leave the people and dog biscuits there overnight. Remove the biscuits from the baking sheets, put them in a sealed container or zip seal bags and store them in the refrigerator.
Tips & Warnings
Water or vegetable broth can be substituted for chicken broth.
