Mulled cider and cinnamon whiskey unite to create a perfect winter sipper. The Fireball flavor may be subtle here, but there’s no doubt this cider is spiked. We prefer using refrigerated cider to shelf-stable cider. Depending on your preferred brand of cider, you may choose to omit the added sugar during the mulling step. This recipe makes 12 servings, but you don’t have to serve it all at once. You can mull the cider, serve what you want, and save the remainder in the fridge.
