All Day Apple Butter

from: allrecipes.com

Ingredients
5 1/2 pounds apples – peeled, cored and finely chopped
4 cups white sugar
2 teaspoons ground cinnamon
1/4 teaspoon ground cloves
1/4 teaspoon salt

Directions
Place the apples in a slow cooker. In a medium bowl, mix the sugar, cinnamon, cloves and salt. Pour the mixture over the apples in the slow cooker and mix well.

Cover and cook on high 1 hour. Reduce heat to low and cook 9 to 11 hours, stirring occasionally, until the mixture is thickened and dark brown. Uncover and continue cooking on low 1 hour. Stir with a whisk, if desired, to increase smoothness.

Spoon the mixture into sterile containers, cover and refrigerate or freeze.
