It was a case of Kerr jars with bands and lids that I picked up a couple of weeks ago.Me either! Where'd you get the lids?
I boiled the apple pieces in the light syrup as well to release a lot of the trapped air in the pieces, but there is always still some.
it was the weak way they sealed, and how they sounded, and the sealant on top of the lids. But to have ALL the jars fail. NEVER have I ever.
