They all sealed almost immediately. 1/2” headspace. You can lift the quart by the lid without breaking the seal. There has to be a little margin for error worked into these instructions right? I’m at 800 feet elevation fyi
I hotpacked tomatoes and processed them in quart jars for 40 minutes instead of the proscribed 45. Jars were cleaned and sanitized with plenty of citric though. Think I’m still ok?
