Bring to a boil, and then reduce heat to low and simmer for 15–20 minutes or until the cranberries burst and the mixture becomes thickened.
Cool and then store in the refrigerator until ready to use. May be made up to one week in advance or frozen for up to three months. Makes 3 cups. A serving is about ¼ cup.
