Hi all, I canned several jars of tomatoes last year (my first time) and put them in my basement thinking it would be cool. Due to our new furnace, our basement isn't very cool, stays a steady like 65-70 degrees. Anyway, some of my jars of tomatoes have mold around the lid. The seal isn't popped, but am not sure if I should use them? Our basement doesn't have mold anywhere else except on a few of my jars. Did I do something wrong?
