With the Presto, I let the canner and jars cool down together a bit (probably actually lowering the pressure) before removing the jars. If I do that with the All-American, I’ll have a lid stuck on with a vaccuum!

I've never had that problem, although a few times the lid did get stuck. It doesn't form a vacuum because the vent that lets the steam out, lets air in.

I think it happens when there's a temperature differential between the pot and the lid. I think if you let it cool all the way, it's not a problem.

When they got stuck I'd use a metal spatula to pry it off. It always eventually came off.

Whatever, you DON'T want to take it off too early. Aside from the potential for burns, the food could spurt out of the cans and ruin the seal.

“. It doesn’t form a vacuum because the vent that lets the steam out, lets air in.”

That’s good to know!

The video I was watching threatened that I had to get the lid off in the first few minutes, I can’t remember how many.
