Nothing better than a cozy and easy slow cooker apple cider!
Cut the apples into quarters. No need to peel or core the apples.
Slice the orange. Note: orange peel can add a nice touch of bitterness that I love in my apple cider, but you can choose to peel the orange to make it less bitter.
To a 4-quart slow cooker, add the quartered apples, orange slices, cinnamon sticks, whole nutmeg, whole cloves, and sugar. Add water to fill the slow cooker. 8-9 cups of water should be enough.
Set the slow cooker on HIGH for 4 hours. 1 hour before it's done cooking, remove the apples and mash them using a fork or a masher. Return the mashed apples, including the bits and pieces and extra liquid, to the slow cooker. Cook for another hour.
Strain the solids with a fine-mesh strainer or cheesecloth. Serve warm and enjoy!
