Ok, all you pumpkin butter fans out there!! I just got off the phone with the University Extension Center of Missouri..."THERE IS NO SAFE WAY TO MAKE PUMPKIN BUTTER OR TO CAN PUMPKIN". I asked her if fruit fresh/vinegar or lemon juice could be added? she searched everywhere...meaning, the Ball Book, and lots of extension centers on line,outside of Missouri and the USDA. She said there is just not a safe way.
I then asked her if you could make the pumpkin butter with half apples and fruit fresh..........she wondered herself. She cannot say yes as all the resources available to her say no. But I am wondering if it would work. she said the reason for not canning it says it has to do with the thickness as well as the acidity level as pumpkin without promotes a bacterial growth that she could not even pronounce. ha I told her if she couldn't pronounce it then I certainly wouldn't know what it was! I also asked her about all the apple butters our forefather's produced? She said, they experienced a high risk of severe illness. She said if there was something you could subsitute it would have been in her resources. So make it at your own risk.
