QuilterMomma, sorry to learn your work was in vain, but you inspired me. I pulled out the manual from my "Mirro-Matic Pressure Cooker." We used to buy the cheap cuts of beef and they always came out fork tender, like with slow cookers, but a lot faster. I checked the lid and seals, and am going to start using it again.
I never used it for canning before, but the instructions given for canning soup stock seem pretty straightforward. Cook it, skim fat, remove bones, pour hot into prepared jars, etc. and process. The news reports of the chemicals used to line soup cans these days is worrying.
I don't know if the new pressure cookers are capable of canning. Just like with sewing machines, always read the manual. ~
