Rinse the cranberries and set aside.
In a medium saucepan, add the granulated sugar, dark brown sugar, orange juice and water. Cook on medium-high heat until just boiling, stirring occasionally. Add the cinnamon and stir.
Add in the cranberries and stir. Cook for about 15 minutes, stirring occasionally. Remove from heat and let cool. *The longer you cook the cranberries, the thicker the sauce will be. For a thinner sauce, remove from heat at 10 minutes. Once cooled, the sauce will be thicker than in the pan.
