Lid popping when I checked for seal the next day
I made peach chutney yesterday, hot ingredients into hot sterilized jars. Wiped the rims. After submerged in boiling water 20 minutes, and sitting placidly on counter all the jars popped but one. Today when checking the seals, depressing the center of lid, the one that had not popped on its own, popped. Now I am not sure if the seal of that jar is good.
Is it OK to store it, or should it be used and refrigerated immediately?
Best Answer
You should either store that jar in the refrigerator or reprocess it with a new lid.
The vacuum formed is not going to be as strong as your other jars and may be temperature sensitive. It may stay sealed on the shelf, but it may not. I wouldn’t risk having to discard the whole jar.

What does it mean when the lid pops after canning?
When you're taking your jars out of the canner, sometimes they will immediately start popping. Generally, you'll put them on the counter and after a few minutes, they'll start popping. The popping sound when canning is a good thing IF it indicates that this lid is popping down. Just leave the jar on the counter.How long after canning do the lids pop?
It can take up to an hour or even longer for a canning lid to seal, and jars should be left undisturbed for a full day before you check their closures. When 24 hours have passed, check the lids.Do lids always pop when they seal?
If the lid \u201cpops\u201d up and down with your finger when you press, it's not sealed and needs to be reprocessed. If it doesn't move at all it's likely sealed. Note: Don't test canned foods until they are completely cooled and you've given them several hours to seal! Doing so might create a false seal and unsafe food.What is a false seal in canning?
A false seal is a weak seal that can happen for a number of reasons. False seals occur when the products are not canned correctly, when jar rims are not wiped clean before processing, or if jars are not filled correctly.Asaf Avidan \u0026 The Mojos - One Day / Reckoning Song (Wankelmut Remix)t

Answer 2
As long as the lid doesn't pop up again, you're OK, I'd say.
IMO the reason that this one didn't pop on it's own could well be because that jar was more full. More full means less air. It's the contraction of the air as it cools which creates the vacuum that makes the lid pop. If there's not enough air, its likely that insufficient vacuum will be generated to cause the pop.
The fact that it did pop when you pressed it re-enforces this. If the seal was bad, it would have let enough air in that it wouldn't stay down when pressed.
Note that I've never made jam/chutney, but am fairly well versed in Physics!
