Crock-pot Apple Butter

Peel and chop enough apples to make 6 quarts or to fill a 5 qt. crock-pot. Place 1qt of the chopped apples in pot and add 3/4 to 1 cup sugar. Keep layering 1qt of apple with 3/4 to 1 cup of sugar DO NOT ADD WATER Add 11/2 to 2 tsp cinnamon 1 1/2 to 2 tsp cloves    Stir well and cook on low heat 8-9 hours with the lid off the last half of the cooking time. Cook until thick and spreadable. If texture is too chunky when cool put through a blender. Ladel into clean sterilzed jar, seal and waterbath for 10 min. This is the 'neatest' way to make apple butter. You can do the same thing in a kettle on the stove but you must stir almost constantly to keep from scorching and it will bubble and splurt everywhere while you are waiting for it to get thick.
