In a pitcher, mix apple cider, pear nectar, and ginger ale and stir well (but gently).
Add cinnamon and stir well.
Add caramel sauce and stir well (it helps if you warm the caramel first).
Place apple slices inside pitcher.
Keep in the fridge for 1/2 hour or pour over ice and serve immediately.
If you want it warm, heat all of the liquid ingredients in a pot over a stove on low heat. Simmer for a few minutes until warm, place apple slices in the pot, and serve in mugs. (Note: It may form some bubbles while simmering)
If you want an alcoholic drink, add one shot of vodka to each individual drink, or 1½ cup to entire pitcher
