Peel and cut apples into small chips. Place all ingredients in the crock pot and stir. Cover and cook on low overnight (eight to ten hours). Remove cover, stir and taste. Add more spices or sugar if desired. Continue cooking for a few more hours, uncovered, until some of the liquid has evaporated and butter has cooked down a bit. Pour into jars and refrigerate. Serve over hot biscuits, toast, scones or eat it out of the jar.
