Peel the apples and discard the peel. Chop into large chunks or use an apple slicer.

Remove the peel from the orange leaving behind the white fibrous pith.

Place the apple pieces, orange peel, cinnamon sticks, whole cloves, and whole allspice into the slow cooker.

Fill the slow cooker with enough water to reach the bottom of the top layer of apples.

Turn it on low and put the lid on. Brew on low for 8-12 hours, ideally 12 hours, or high for at least 4 hours.

Add the sweetener of your choice and stir to mix together and melt.

Using a potato masher, mash all of the apples in the slow cooker.

If a clearer cider is desired, strain the cider through a fine mesh sieve or cheesecloth.

Let cool slightly and taste. Add more sweetener if desired. For a concentrated flavor, boil off some water on high with the lid off.

Store leftover cider in the refrigerator for up to 5 days.
