Peel, core and slice apples thinly. In 5 quart crockpot, pour in the apple juice or cider on bottom, then layer in the apples, pack firmly, put on the top and put on low, cook for 12 hours, stir the apples,then add sugar and vinegar. Next morning add cinnamon, remove the lid, put on high and cook about another 4 to 6 hours. Use either a hand mixer or emersion blender to blend thoroughly. It the mixture is too loose cook until you reach the decided consistency. This should make about 8-10 1/2 pint jars. Sterilize jars, lids, fill jars, wipe rims, place lids and bands, put in hot water bath for 20 minutes after the water boils. It can also be frozen in freezer jars.
