The instructions are steam for 20 minutes and cook under pressure for 2.5 hours. Now my usual pressure cooker is my mum's old Prestige Ultra which has a valve you turn from steaming to pressure cooking, that's OK.
I have another pressure cooker which I'd like to use to save time (5 puddings) which I don't have instructions for, it's one a bit like this with just the one pressure valve in the middle. Do I take the weight off for steaming and then put it on for pressure cooking? And do you really run it under the tap to release the pressure?
