Renowned baking writer Mary Berry and professional baker Paul Hollywood explore the history of the Great British wedding cake. They look at its dramatic change through the eras, from the earliest Tudor creation and the extravagant Victorian period, to wartime Britain, the affluent eighties and the present day. Mary and Paul also set the ultimate challenge to the three finalists from 2010's Bake Off, to make and bake two spectacular wedding cakes each, one traditional and one contemporary, in just 16 hours.
