Note that the orange slices may fall apart as they get close to being done. Not to worry; they’re just going to be chopped up later. If you want, you can substitute 3/4 cup (180ml) orange juice for the water that you cook the cranberries in. I use dark rum, but whiskey, bourbon, or an orange-flavored liqueur, such as Grand Marnier or Cointreau, would work nicely in its place. You can double or triple the recipe if you wish.
