This simple fall recipe is a must have to make every year during the crisp autumn season!
Cut the orange or citrus into thick slices (I usually cut one orange into 4 slices). Press 5-8 cloves into each slice; set aside.
In a large pot, combine the citrus pieces, cinnamon sticks, and cold cider. Bring the mixture to a boil, and reduce heat. Simmer for 45 minutes to 2 hours (taste testing to determine how spicy you want it).
Remove and discard the citrus and cinnamon when the cider is spiced to your liking (leaving them in there too long will make the cider bitter).
Serve hot immediately, or allow the cider to cool to be served cold at a later time.
I like to save the cinnamon sticks from mulling the cider to use as a garnish. The heat and moisture cause the cinnamon to expand, and I think it looks really cool when it's done.
