Wash, peel, and chop the apples.
Combine all of the ingredients in a large pot.
Bring the mixture to a boil. Reduce the heat to low, and cook until the apples are soft. Purée the apples with an immersion blender* until smooth, and simmer for 6-8 hours, or until reduced, thickened, and a rich reddish brown colour.
Can immediately in sealed jars, or store in containers in the fridge or freezer until use. Use as you would any fruit jam.
*If you don’t have an immersion blender, you can process your apples in a food processor or blender before cooking instead.
