First time making Christmas puddings this year 
. I have 3 puddings to steam. I have 3 large pans. One of them is a pressure cooker with no weight that I just use a large saucepan mostly - cooks a bit faster with the sealed lid but I've never thought further about it...
I've put the biggest pudding (for the whole family on Christmas day so a bit anxious about it anyway) in the pressure cooker already and am now having a right old panic. Firstly, I sealed the lid with foil before adding the plastic clip on lid - the way my recipes say for steaming method. Secondly - do I need to adjust the cooking time? The recipe says 6hrs. Pressure cooker advice says reduce by 1/3 but this is for real proper pressure cookers, not ones with bits missing like mine...
Help! I really don't want to have messed this up!
