Wash the apples and orange and roughly cut them into quarters, no need to remove seeds or stems. Place the cut fruit and spices in the bowl of your slow cooker. Add water until it's about an inch from the top of the bowl. Cook on high for 4 hours.

When you have an hour left in the cooking process, use a potato masher or a large spoon to crush and mash the apples and then let them continue to cook.

After 4 hour strain the cider to remove all of the fruit. I strained it through my normal pasta colander and then again through cheesecloth to make sure it was all cider and no chunks.

Give your slow cooker bowl a quick rinse to remove any extra pieces of fruit or spices and then return the strained cider to the bowl. Heat on low heat and add sweetener of your choosing, such as brown sugar, honey, or maple syrup to taste, stirring well to combine. Serve warm with additional orange slices and cinnamon sticks as a garnish.
