When you get a chance get a pressure canner. You can find them at yard sales, Craigslist, ebay. I’ve canned meats, soups, stews. At 10 to 15 lbs. PSI (depending on your altitude) It will kill anything including botulism. You don’t need to redo your tomatoes
Already have one. I never fire it up for tomatoes. The water bath always works just fine.
Be careful throwing that pressure cooker stuff. You are inviting a visit from the Feds.
