I wasn't doing the canning, that was all done off site by the lady who brought the stuff already in jars. I had brought a large pressure cooker as part of the brewing kit and that was to serve double duty for canning, but I think there was also another large pot, like you say water bath canning.

The mason jars I brought up empty left with a clear liquid fuel additive which came from a process involving sugar, corn flour, yeast...

Seems a jar of that stuff on a value by weight and barter ratio is pretty good in comparison to premium cuts at the butcher shop in Safeway. Yep, premium fuel additive....
