Cut 1/3 of the orange off and scrape pulp from the insides of both pieces. Take 1 biscuit and mash out. Sprinkle a little powdered sugar and cinnamon and layer with another biscuit and repeat. Usually takes 2 or 3 biscuits. Roll up the layered biscuits and put into the hollowed orange. Add about a tablespoon of powdered sugar on top and a teaspoon of milk. Replace top and wrap in tin foil. Place in coal of fire for about 30 minutes. Remove, unwrap, pull top off and out pops a delicious cinnamon roll with a hint of orange.
