I believe my wife has me trained pretty well... I'm pressure canning left over ham beans. Just too good to not can. I really like meals in canning jars
Well I've had my first bad jar with a crinkled lid. I asked my wife what happened and she said aww that's to bad... I don't know what happened to cause that - sometimes it just happens to a jar or two. Even though after I removed the ring and found out the lid had sealed, I threw the jar away anyways just to be safe.
The remaining jars are ok though.
Anyone know the cause? Did I get a little to heavy handed when I screwed down the ring maybe?
I have had that happen in the pressure canner. But I find it immediately when the pop! and seal, before I put them up. I just put the jar in the refrigerator and use it first.
I've had that happen once when doing tuna. I treated it like lids that didn't seal. Wiped down the rim and placed a new lid on. Reprocessed in the next batch. I mark them so I know which they were.
Sometimes it's from tightening down too tightly, sometimes it's the quality of the lids. If you had more then one of the same kind of lids buckling, it could be the quality of the lids. Just one? Mostly likely it was too tight.
No worries...like everyone else said, just get a new lid and reprocess if you find it in time. A good rule of thumb....remove all your rings prior to storing and check the seals by lifting up on the edge of the lid to see if all have sealed. If you leave your rings on, you can have a sort of false seal sometimes and not discover it until it's too late to rebatch it.
