Yes, over tightening the band will do it too. I forgot about that one, thank you. That's usually a problem with those very new to canning.
A whole bunch of tomatoes out there that should be ready to pick tomorrow. Storms are coming through tonight, so I may pick them tonight and let them ripen in the heat of the barn.
I have 4 qts of puree from yesterday left over, so I think I'll make up some tomato soup and get that sealed up.
All that's left in the garden is Mustard, and tomatoes, so from here on out, it's all tomato talk.
