Add all of the ingredients to a medium saucepan and bring to a boil.
Simmer over medium heat, stirring occasionally, until most of the berries have popped. Mash berries to reach desired chunkiness. Sauce will thicken as it cools.
Refrigerate for 4 hours or until ready to serve.

Notes
The cinnamon is optional, but we love the warm, cozy flavor it adds to the cranberry sauce.
