Follow the four semi-finalists as they wrestle with savory canapés, charlotte royale and opera cake.

Three French bakes stand between the four semi-finalists and a place in the final. The Signature challenge raises the stakes, tasking the bakers to make three different types of savory canapés in just two-and-a-half hours. One must be choux and one another type of pastry such as shortcrust; the third is baker’s choice. The Technical challenge is the complex charlotte royale, which combines a perfect Swiss roll surrounding a delicate bavarois, set with gelatin to hold a firm dome. The final is a truly iconic French patisserie: the opera cake.
