Combine flour, bulghur, and powdered milk, then beat into yeast mixture. Knead dough for 4 minutes. Divide into 3 equal portions. Set 2 of the portions aside, covered with a towel. Cut into bone shapes.
Place biscuits on an ungreased baking sheet covered with cornmeal.
Brush with egg wash. Repeat with other 2 portions. Set biscuits in a warm place to rise for 45 minutes. Preheat the oven to 325 F and bake the biscuits for 45 minutes. After all of the biscuits have been baked, turn off the heat and leave them in the cooling oven overnight to harden.
