Oh My, I think my co-worker screwed up his green beans again...
I couldn't find my old post from last year so I'm starting another.
A co-worker canned his green beans last year in WB. He came to me asking about why they were spoiling. I told him to buy a pressure canner. He did.
Now, he has green beans spoiling again! I asked him did you use the pressure canner, yes. Did you add a little acid, yes, 1/4 cup of 5% vinegar to each quart. Did you process for them long enough, yes, 1 hour. Did you let them cool before removing the PC lid, yes.
I think I may have found the answer with this question: At what pressure did you can them, He said it is a weighted PC and he put his glass top stove on high and it only made the weight rock but not release any steam.
I've read on here that problems arise when using a glass top stove.
