Yes, you can substitute 5 spice powder. It is just more convenient. The 5 spice powder I use have Cinnamon, Star Anise, Licorice, Shallots, Ginger or Galengo (a spicier ginger from SE Asia), Sichuan Peppercorns (or Black Peppercorn). OK, its 6 spice - I found an easier recipe and have tested it. I will post it after this one.
