Add all ingredients to a large saucepan over medium heat. Stir and cover until mixture begins to simmer and cranberries begin to pop and foam. Taste for sweetness. If too tart, add sugar by the teaspoon until your desired sweetness is achieved, and stir until sugar dissolves.
Remove from heat and store in an airtight container in the refrigerator until ready to serve. Sauce will thicken as it cools. Best if allowed to chill for at least a day for the flavors to mingle.
