Combine apple cider, cloves, cinnamon and extract in a small sauce pan over medium heat. Bring to a gentle simmer for 10-15 minutes.
Strain out cloves, mix in rum and set aside.
In a small plate combine sugar and cinnamon.
Wet the rim of the serving glasses with some extra rum and dip into sugar mixture to coat the entire rim.
Pour cider into glasses and serve warm.
Preheat oven to 225 degrees.
Place apple slices on a parchment lined baking sheet (slice the apple whole, do not core).
Sprinkle with cinnamon and nutmeg and bake for about 2 hours, flipping slices half way through. Watch carefully after 1 hour 30 minutes to make sure they don’t burn. You want to remove them when crispy, not burnt.
