5 c  Apples (cooked and mashed)
5 c  Sugar
2 tb 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 and serve.
