Our Christmas dinner feels like it's been around forever, but in fact much of it is a surprisingly recent invention. In this one-hour programme, Jimmy Doherty goes on a personal journey to discover where the food on our Christmas plate historically comes from and how it has evolved in the age of mass production.

To find out, Jimmy has spent months growing and making his own traditional dinner from scratch; all to discover if it tastes better than the modern turkey and trimmings provided by the giant supermarket farms and factories that go into overdrive to feed millions at Christmas.

It's daunting enough cooking one Christmas dinner, but Jimmy's juggling two in this ambitious, noble and experimental festive cook-up. Friends, family and the farmers who've helped him along the way gather for a festive feast that is spiced further by the not-so-helpful appearance of his best mate Jamie Oliver. Together they decide which one's better: the dinner we used to eat back in history...or today's familiar supermarket favourite.
