I just put some chili to process. I'm doing it @ 10LBs for a ridiculous amt of time according to Stocking Up for beef canning. But I have a problem that I completely forgot about. My older pressure cooker is much older than the one DH gave me a few years back....it belonged to my grandmother. Well, I don't think the seal is very dependable, so even though I'm using it for the pint's, I am not sure if I will really have the amt of pressure I need. Granted, its not just beef I'm processing. There is salt and other seasonings and then a good amt of tomatoe product, so I'm hoping that allows me some acid to keep things safe. But I think I won't let the pints get very old at all.
Now the quarts shouldn't be a problem. That seal is well intact.
