Hi I believe there is an old English saying "He had his hand on the pan" For example, your mum sends you to get a pound of flour. The shopkeeper weighs it out but, slyly, keeps a finger on the weighing pan so that you do not get a full measure When you get home, your mum, seeing that you have not got a full pound, says "He must have had his hand on the pan" I think that is the metaphor used here. Oliver is saying "We're going to have to cheat a little here".
