Lid deforms?

My first batch of pickled jalapenos turned out perfect. My store ran out of regular pint jars so I had to buy wide mouth for the second batch. About 8 of the 11 had a loud pop and a visible lid deformation while bringing the full jars up to boiling. 12hrs into cooling and the dents look less severe, but I haven't tested them to be sealed. Are they OK?

Hmm, I've never seen this before. I'm wondering if maybe you over-tightened the lid rings before putting them in the boiling water. Do remember if you lightly finger tightened them or if you tightened them all the way?

In the meantime, the surest and safest way to know whether the lids sealed properly (I'm guessing they didn't) is to do the jar lift test that I demonstrate in Lesson 2.

If the lid comes off easily, then they did not can properly and unless you put them straight into the fridge after you canned them, I wouldn't recommend eating them. It's so much better to be safe than sorry.

You're correct about the tightening of these lids, I probably over did it a bit before putting them in the boil bath. While still sealed, I took the jar with the most dented lid and put it in the fridge overnight, for use the next morning (I prefer the japs cold for my salads). When I removed the band this morning, the lid aced the test you mention in step 2. I had to almost pry it off the jar.I looked on the underside of the lid, where the seal meets the jar, and did not find a noticeable malformation that could indicate a bad seal.
In hindsight, I probably should try your test on a jar before refrigerating it overnight, just in case the temperature decrease creates a new/better seal than the jar experienced the last 22 days in the bottom of my pantry.

I'll throw out today's jap ration, and check another jar when I get home. If it passes, I'll eat'em. If I don't reply again reporting botulism, IT WORKED!
