1Take the oranges and stud them with whole cloves and bake them at 300 for 30 mins. Combine apple cider, orange juice and pineapple juice in a very large pan. Heat. Add oranges to liquid and add cinnamon sticks. May be kept warm on burner on low. Serve hot to drink. Never tried it but maybe a slow cooker would work really well.
NOTE: of course you can add alcohol of your choice to kick it up a notch.
