Stick cloves into an orange. If you want a more intense orange flavor slice the orange in half first. Put into your pot.
In the crock pot mix the brown sugar and apple cider until dissolved. Add whole cinnamon sticks. If you want to add a spice bag add it at the end and submerge.
Cook on low for 4-6 hours and then enjoy. Leave on "keep warm" after that so you can enjoy it for hours on end.
