3/4 c. hot meat juices
1/3 c. butter
1/2 c. powdered milk
1/2 tsp. salt
2 tsp. sugar
1 egg, beaten
3 c. whole-wheat flour

In large bowl, pour meat juices over butter. Stir in powdered milk, salt, sugar, and egg. Add flour, 1/2 cup at a time, mixing well after each addition. Preheat oven to 325 degrees. Knead 3 to 4 minutes, adding flour if necessary to make a very stiff dough. Pat or roll to 1/2 inch thickness and cut out biscuits with dog-biscuit cutter or other cutter. Place on greased baking sheet and bake for 50 minutes. Allow to cool and dry until hard.
