Ok... to all canners and people looking to can.... “cheap generic” canning lids are NOT a worthwhile investment, at least for pressure canning. They can’t handle the pressure and buckle, almost every time. They “might” suffice for water bath canning (jams, pickles, salsa, tomatoes...). Don’t take the shortcut on lids for pressure canning, only buy the real thing with the expensive “ball” lids. I had 4 ball lids and two generic in this batch. 2 buckled, 4 sealed. You can guess which were which.
