Clip top jars not sealing

Those jars don't normally create a vacuum. They are for things like jam, picallili, things in oil and/or vinegar.

If you wanted to create a proper vacuum seal, you need the normal kilner type jars and screw on lids with separate metal lid or the metal lid like you get with quattro stagioni jars.

Yes like -t says (and other posters), need some screw top jars hun.  None of my various sized clip kilner jars create a vacuum - just stood in the kitchen opening/closing them all (with hubby standing there thinking I'm having a mental breakdown) 😹

May not be relevant, but I've found a big difference in seal between proper, branded Kilner jars and the supermarket equivalent.  I would use the former if I want a properly air-tight container and the latter, when it is just to use as a storage jar.

Oh yes they do.

They should create a vacuum when hot filled.
Not when you are opening & closing them in the kitchen.

Okay, kilner have a video called 'how to fill and seal your kilner jars' which shows them being put in a pan of water and heated for 30 minutes to create the vacuum, might be worth a look?  If you have followed the instructions they provide in that video and the jar is still not vacuum sealed then you might want to complain to kilner direct?

It may be apocryphal, but I remember being told that one of the reasons that we beat Napolean at Waterloo was that we had beef in cans and these stayed good through the campaign, whereas the French had it in Kilner-type jars and the food went "off".

...Of course, history won't have recorded how many of our guys went on to die of lead poisoning in later life!

Yes it sounds like a product quality issue.  I store coffee beans in Le Parfait jars in the freezer and they always open with a good pop

That's interesting. I was taught that Napoleon expected the French Grande Armee to forage for food and fodder rather than be supplied by a baggage train, thus removing at a stroke the problem of the baggage train keeping up with the army.
This, I was told, was why the Russian tactics after Borodino were so effective because it meant there was nothing to forage for miles in any direction.
I was also told that one of the things the Russians did was to utilise the winds when they could to waft cooking aromas across the route of the French march and have horsemen ride close to taunt the soldiers about their hunger and demoralise them by pointing out that Napoleon didn't provide for them ergo he didn't care for them and why don't you desert etc.
I do find all this interesting because it shows that much was known about Napoleon's methods of making war and that the Russians were very imaginative in their tactics and managed to convince both their army and their population to participate wholeheartedly.
Evidently the Russians of that time were past masters of communication and persuasion and this is not a quality that present day Russian leaders seem to have.
Anyhow, getting back to Waterloo, perhaps Napoleon concluded while musing on Elba that it would be a good idea to provide some food for the troops in the future to keep up morale
