Tom Kerridge welcomes the last three teams to the competition for the fifth and final heat. Chefs from a fine-dining restaurant in Liverpool are up against a team of chocolatiers from Leeds, and a side which will be competing for Wales in the culinary Olympics. In the Miniatures they must make dozens of tiny fruit tarts, coconut dacquoises and cubed cakes of their own design, and for their Showpiece they must reinvent chocolate cheesecake.
