Just one more thing on that. I do it once the pressure/temperature gauge looks like it’s all the way down, at zero.
Lifting it slightly would verify it is or not and yet, if the canner still had a little pressure in it, wouldn’t be enough to make the jars leak.
I have found from experience that trying to take the cover off the canner too soon is just felt too risky. Never got burned but it just was too hot for me to feel comfortable trying it when it was that hot, even with potholders. The potholders were just too bulky to be able to manage unscrewing the knobs anyways.
That makes sense. In my one-time usage of the canner, it has a lot more metal to it than the presto did. So it will retain its heat a lot more as well. it ‘felt’ more robust and more than a little scary, although I do love the way it looks
