The remaining 12 contenders face a daunting challenge as they cook for previous finalists and winners of the competition, working under head chef John Torode in their first restaurant-style service. They are asked to design a stand-out dish for the three-course menu and have just 30 minutes to deliver their food once the orders have been taken. The diners include Dhruv Baker, Mat Follas, James Nathan, Steven Wallis, Peter Bayless and Thomasina Miers.
