Put the cranberries, orange juice, orange zest, pomegranate juice, sugar, cinnamon, and allspice in a medium saucepan over medium heat. Bring to a boil, and the berries will start to burst. Reduce the heat to a simmer. Cook for approximately 8-10 minutes. Take it off the heat and use an immersion blender or potato masher to blend to the consistency you prefer. Enjoy!
