What drives people to stake their livelihood on sponge? Three cake makers discuss the pressure and privilege of creating show-stopping centrepieces for major celebrations. From a perfect replica of a cow to a cake hanging from the ceiling, they reveal the engineering and money that go into some of the most formidable bakes. Emily Thomas meets Claire Ptak, owner of Violet Cakes, who made the cake at Prince Harry and Meghan Markle’s wedding, Pardeep Gill from Sweet Hollywood which specialises in wedding cakes for the Asian community in the UK, and Asha Batenga Jumba from Cakely Uganda in Kampala. Plus, we’ll hear some toe-curling stories of baking disasters.
