I just had 6 hours of fighting this lid issue. Each with a leak. I even tried a laser level. Yes, I lost sanity today. Thank you beyond words for this post! I will attempt tomorrow.
I have a question about headspace for canner experts. I am struggling to attain sealing for a soup with loads of veggies, tomatoe based, the meat is chicken (roasted and smoked thoroughly). I canned for 90 minutes at 15 lb. Half would bot seal amd those had soiled lids. The headspace was 1". Should I increase that headspace to 1 ยน/4?
