i like pressure cookers, i am a late in life convert. i bought one off the shopping channel. the modern ones are great. my mum had one when i was a kid. it was like a steam train reaching the terminus in the kitchen. scary. i always had visions of the thing on top shooting off like a bullet and killing someone three houses away.

however
because the water doesn't escape, i find it hard to calculate how to stop the mix getting a bit watery. what do you do or add to stop the watery effect?
