Pressure cooker - quick question

[ChristmasAlreadyOver]

I'm using but fir the first time

The instructions say when they pressure is up "lower the heat source" BUT

how much do you lower it to?
Is making a noise and steam is coming out...is it low enough????
Aaaggghhhh

Thanks

I turn the gas to the lowest setting - most will still steam and whistle. Remember to make sure it doesn't boil dry whilst it's on the hob - it can happen really quickly even on the lowest heat. Oh, and remember to ensure the pressure is released before taking the lid off - if you have to force it, there's still pressure in there.

Thanks.
I think I could have turned it down a bit more but it was DELICIOUS

Pleased it was okay in the end. Pressure cookers are the work of the devil!

It was so good I'm using it again tonight
