I’m glad you found a use, so they weren’t a waste.
I was ridiculously confident when I first bought them. I think I got 12 boxes. I thought how hard could it be? My first batch nothing sealed. Then I panicked because I had all these worthless lids. But that made me practice and practice and figure out what I was doing wrong.
It ended up I had gotten completely lazy with the ball lids. Those things sealed no matter what. With the tattlers I actually had to follow canning directions. When I did that, I had much better success.
The O-rings from that first batch I haven’t been using. The ones I use for pickles and jams are from newer batches.
The old ones still stink. I should just melt them down into a doorstop or something.
