Hi Laura, I am living in China and have just bought a midea electric pressure cooker. However after getting it home I’ve discovered the max pressure is only 40kpa which I think corresponds to about 6 psi. Could you tell me whether there is a simple way to adjust recipe times? (I am also at 6000ft which I understand means I need to add 25% to cooking times). Thanks.
Yes 40 kPa is just under 6 PSI
What you need to understand is that a pressure cooker rating is only part of the scenario.
At sea level, atmospheric pressure is about 15 PSI. When you use a 15 PSI pressure cooker at sea level, you are really cooking at 15 + 15 = 30 PSI.
When you are at 6,000 ft, atmospheric pressure is about 12 PSI. So when you use your 6 psi pressure cooker, you are actually cooking at 12 + 6 = 18 PSI. This is only just above normal open pot cooking at sea level.
So your best bet is take the open pot cooking times and subtract about 20% then experiment from there.
