Inside the Christmas Factory 2018

In this Christmas special, Gregg Wallace visits a factory which produces two million tins of festive chocolate assortments a year. Cherry Healey is producing other festive treats. She travels to Germany - the home of so many of our Christmas traditions - where she joins a crew of 35 ornament decorators, applying glitter and paint to an army of glass Santas. Historian Ruth Goodman is on the trail of the Christmas turkey.
