Help...bulging jar lid!
I just canned my first batch of tomatoes. I see from some reading on here all that clearish tomato juice with tomatoes bobbing up out of it is ok. But when I took my jars out of the pressure canner I noticed that 2 out of 7 had lids that were bulging up so much on the top that they are bent! I did NOT overfill them based on the recipe and instructions. Why would they do this? I assume they won't seal properly now since the lid is bent. Ugh. Could the problem be that I used the Golden Harvest canning jars and their lids from Big Lots? Just cheap crap?
