This sauce is truly easy to make, and it's absolutely gorgeous and delicious, and it fills the house with the most tantalizing aroma of tart berries and warm spices and sweetness.
Place the cranberries, sugar, and apples in a large pot, covered, over medium heat. Stir occasionally until it comes to a full simmer, then turn the heat down to low and cook, covered, for ten minutes.
Turn off the heat, stir in the spices, and cool to room temperature before refrigerating.
