How to test a pressure cooker? (evaporation? cook a potato?)

mike2401 | Jan 30, 2013 10:52 AM

To correct what appears to be a lack of pressure problem, I want to do a test-run tonight.

My thinking is to put 2 cups of water, attain pressure (on high-15psi), lower the heat a bit on my gas stove, and let it run for 30 minutes, then measure how much water is left.

Please take a guess as to how much water should be left? Should I lose 0.5 cups, 1 cup, 1.5 cups?

Assuming the pressure cooker performs as expected, I'd like to perform an actual cooking test: e.g. cook a whole, medium sized sweet potato and confirm that the cook times are in line with expected cook times.

It seems like I need both tests because what if I don't lose much water on the first test, but that's because it's really not under much pressure.

Thoughts?

Thanks,
Mike
