Ok guys, so I need some help here. I'm canning with an electric pressure canner, using ball jars and tattler lids. I have canned one batch of stew (something that I have canned repeatedly) and some ground beef (first time). I'm not new to canning, I followed all the standard stuff. My question is this - ONE and only one jar from each batch is not bubbling like the rest. The seals are good, but no bubbles. I've never run across anything like this, and I can't find anything definitive online or in any of my books that says either "no bubbles, it is not good for x reason" or "no bubbles is fine". I've always had bubbling in my jars. To be safe, I'm obviously not going to trust them until I have some sort of answer, so - anybody run across this? Or have a source that I can reference to let me know what the deal is?
Thanks in advance.
