So, I've made the Nigel Slater one and he wants it steamed for 3&1/2 hours.
However, damp problems in our flat were a prime concern to my DP (and, tbf, me too) so his mother said she'd lend us her pressure cooker. The booklet that came with it has instructions on steaming puddings by weight and doing the 1&1/2 litre sized pudding that Nigel wanted was too big, so we've split it into two, which come in nicely at just under 2lb in weight each.
Now the booklet says that pressure cooking should reduce cooking times by a third but the pudding instructions say to cook for 3 hours. If Nigel wants it done for 3&1/2 hours, and the pudding is smaller too, what should we do?
And does it really matter if it is steamed for too long?
