Not just let it boil though.  From my very recent xperience, :lol:, it makes a big difference letting it come to a full on steaming for at least 5 to 10 minutes.

Yes, steam must escape enough to totally replace all the air.  If you don't properly vent the pressure cooker, you only have hot air inside and we all know that you can't sterilize in an oven at 250F.

Venting replaces the air with steam, which then transfers heat to the substrate.

Failure to do this will result in incomplete sterilization.

Good info :thumbup:

While we're on the subject of correct PC best practice, are there any opinions on how much water one should use. I generally use about 3 quarts in a 21 quart AA. It sits just below the trivet line (I have my own, its much taller than the supplied ones)and doesnt even come close to boiling dry over 2 hours.

I use 1 pint of water in my AA930, comes right up to the trivet.
