All-Day Apple Butter

5 1/2-6 lbs. apples, peeled, cored and finely chopped
4 c. sugar
2 t. cinnamon
1/4 t. cloves
1/4 t. salt

Place apples in a slow cooker. Combine sugar, cinnamon, cloves, and salt; pour over apples and mix well. Cover and cook on high for one hour. Reduce heat to low, cover and cook for 9-11 hours or until thickened and dark brown, stirring occasionally (stir more frequently as it thickens to prevent sticking). Uncover and cook on low for one hour longer. If desired, whisk with a wire whisk until smooth. Spoon into freezer containers, leaving 1/2 inch headspace. Cover and refrigerate or freeze.

This is very tasty. Ask Blake. He and I made this for a marketing project when he was in 5th grade.
