I am going to confess, before you discover, that I am on Masterchef next week. Now this is an innocent and popular piece of BBC entertainment (for non UK residents, it's a "cook-off" that runs over many weeks on the television between a number of amateur chefs); but it is not part of my regular viewing.
I am going on the programme not to cook, you will be pleased to know, but to be part of a group of historians who are cooked for by some of the leading contestants.
And before you say, "why on earth...?", let me answer.
