“That size is good for pints, and half pints. You can’t do quart jars in it, IIRC.”
According to Presto, it holds 7 quarts.
Good to hear. I only ever did pints because it made me "feel" I had gotten a lot more from my garden, than had I done quarts.:o)
That's for pressure-canning of quarts, only; not water-bathing quarts, though. We have the 16 quart Presto, and an older 21-quart Mirro, plus pressure pots.
You can use it to also water-bath pints or smaller; but it isn't deep enough to water-bath quarts. The 22 quart is deep enough for all of that; and it comes with a bottom-rack (they all do), so eliminates the need for a separate water-bath canner.
And, of course, either also allows you to use it for pressure cooking, or to even use it as an extra, large soup or stew pot.
