Combine 2 1/2 cups of barley flour, 1/2 cup powdered milk, 1/2 tsp. garlic powder, 1 egg (beaten), 1/2 cup chicken broth, 1 small jar of strained chicken baby food. Mix well and flour if needed. The dough should be firm. Roll out on floured board to a 1/4″ thickness. Cut into shapes and bake on a non-stick cookie sheet for approx. 30 minutes. These should be a very hard biscuit, suitable for a satisfying crunch.
