Your mention of storing things in canning jars reminded me of something.
Do you know that most Classico brand pasta sauce comes in mason jars?
The jars are found in different sizes depending on the product - 8oz, 16oz, 28oz, 32oz, and they all take a standard Ball/Mason screw on top band and lid.
We have reused these jars for water bath and pressure canning for years and never had a problem.
We buy a few jars now and then when the local grocery stores have a buy-one-get-one sale on Classico a few times a year.
But most of our jars came from friends and relatives or people we saw buying the sauce who were happy to save their empty jars for us.
For pickling or short term refrigerator storage we reuse the original one piece screw on top with no problems.
Oh yeah, I love those jars. I have friends that give them to me. I also get jars from local honey from Those same people. I think they are similar.
I have used them for storing pickled beets stored in the refrigerator. I have never pressure canned or water bath canned with them, not yet. I’ve read they are just fine for waterbath canning so I’m thinking I will do that next year when I have produce ready. I’m glad to hear pressure canning has worked out OK with them, if I run out of mason jars I have an alternative now :-). Mason jars can be crazy expensive. Especially with as many as I use.
I got really lucky when I moved here, a lady was selling a whole bunch of them on craigslist for four dollars a case. That’s about half price so I was happy enough with it. But I’m always on the lookout for more and cheaper!
