Crock Pot Apple Butter

5 1/2 lbs apples, cored and peeled and finely chopped
4 cups sugar
2-3 tsp ground cinnamon
1/4 tsp ground cloves
1/4 tsp salt

Place apples in a large bowl, combine sugar, cinnamon, cloves and salt.  Pour over apples and mix well.  Place in crock pot, cover and cook on high for 1 hour.  Decrease heat to low; cover and cook on low for 9-11 hours or until thickened and dark brown.  Stir occasionally.

Uncover and cook on low for 1 hour longer.   If desired, whisk until smooth.  Spoon into freezer containers, leaving 1/2-inch head space.

Cover and freeze
