First things first, don't fret about the cinnamon sticks, cloves, or orange slices. When you scoop the hot cider into glasses, just drain these out (or scoop them out prior to serving). Or garnish your drink with the orange slices and cinnamon sticks!
Add all ingredients in a large pot and simmer as long as you need prior to serving! You can add more apple cider if the heat causes it to reduce a bit.
