Slow-Cooker Apple Cider Tips
Can you cook slow-cooker apple cider for longer than a few hours?
After a few hours, you may want to pull out the cheesecloth full of spices so that they don't start to overpower the flavor of your slow-cooker apple cider, but you can keep the cider on the warming setting in your slow cooker for a while longer if you want to keep it hot for a fall gathering.
How can you make slow-cooker apple cider alcoholic?
While our slow-cooker apple cider recipe already calls for cinnamon sticks, cloves, allspice and orange slices, you still have some options if you want to add even more flavor! If you want to add more spices, star anise would be an obvious choice. Otherwise, add some cranberries for a little more holiday flavor. Add an apple slice to each mug of slow-cooker apple cider for a pretty garnish! If you liked this slow-cooker apple cider, try more of our apple cider recipes.
