Peel, core and chop apples, and fill slow cooker until it’s heaping full. Place remaining ingredients in a slow cooker with apples. The amount will reduce as it cooks. Cover, and cook on high for 1 hour, then lower heat and slow-cook for 4 hours. Remove lid, and continue to slow cook an additional 1/2 hour to an hour or until thick and brown with no liquid left. Place in hot sterilized jars. Set in hot-water bath with lids on for 10 minutes. Boil until seal is secure, and set aside to cool.
