5 c. apples (cooked and mashed)
5 c. sugar
2 tbsp. vinegar

Boil applesauce on high heat, then add sugar and vinegar. I hold the cinnamon until last 1/2 hour because I think it evaporates some. Cook on high heat (about 4 hours) until the apple butter is as thick as you want it when you cool a sample in the refrigerator. You don't need to stand and stir this. Just when it is boiling hard, once every hour or so.
