I have a bought Xmas pud - weighing just over 2lb or 950g - a luxury one from the Co-op. But...my DH has thrown out the cooking instructions!! I was feeling really organised but can not face another trip to the shops to peer at the back of other Xmas puds and we have our main Xmas meal tomorrow! Could anyone help please? Do I pierce the film and how long does it take to steam? Thank you and a merry Christmas to all!
