In a large glass, combine the ginger ale and apple cider. Drop in one or two scoops of vanilla ice cream. Sprinkle with nutmeg and cinnamon and drizzle with caramel sauce. Serve immediately!
Notes
Apple Cider: if at all possible, try to find freshly pressed apple cider, the "real" stuff - it should be dark and murky and absolutely beautiful, not the clear liquid that basically looks like apple juice. It's usually around only in the fall season and you can often find it at local orchards (or great grocery stores). Use the clear stuff in a pinch but the deep apple flavor won't be quite as strong. Chilling the Glasses: also, I like to chill the glasses in the freezer for about 15-20 minutes beforehand. It helps keep the float nice and chilly. Caramel Sauce: storebought caramel sauce works, but I like to use this divine caramel sauce or the simple version from this recipe.
