Notes
You can use the saute function to reduce the apple butter to your desired thickness instead of the slow cook function. This will reduce the time but is more hands on.To convert to a slow cooker recipe, leave out the water and cook on low for 6-8 hours (or high 3-4 hours) in place of the pressure cooking step.
