Oranges
Orange OR orange-colored sorbet
Powdered cinnamon

Cut the oranges in half. Remove a thin slice from the base of each half so the halves will stand up without tipping. Scoop out orange insides and fill shell with sorbet. Freeze each half in its own freezer bag until sorbet is very firm. Serve frozen. Just before serving, dust the top of each surface with powdered cinnamon.
