In this Christmas special, Jimmy Doherty, Kate Quilton and Matt Tebbutt explore how the food industry brings the taste of Christmas to our tables. The number one complaint at Christmas is a dried-out turkey, so Matt turns to science for the answer. His experiments include cooking upside down and even strapping ice packs to the bird, but will any of them deliver? Kate gets the tough job of investigating pink champagne. It's becoming a preferred option at Christmas, but what makes it pink? And who knew that the wrong temperature could mean a trip to A&E from an exploding cork? Jimmy also faces explosions, with chestnuts. They should be roasting on an open fire, but how do you stop them going off like bangers?
