You could do it by putting your filled jars in a pressure cooker.
You would need to be certain all parts of the contents were heated
through.

Have you never used a pressure cooker?

You would need to be certain they were cool (unpressurised before
opening the pressure cooker.

Nobody who has ever used a pressure cooker would find it remotely
difficult to depressurise or cool.

So even then a bit dodgy.

Using a pressure cooker is not in the least bit uncertain difficult
or
dodgy; just unnecessary in this instance.

Clearly you are one that needs to be made aware of the dangers.
If you rapidly depressurise a pressure cooker and there is a closed
container inside, the container may explode due to over pressure
and/or thermal shock.



Careful here!
Janet is the expert on everything. It likes to think so, but nope it is a
dope.
