Double Michelin-starred chef Michel Roux Jr and Masterchef judge Gregg Wallace are on the hunt for a young chef who wants to make it to the top of the culinary world. The semi-final week continues as the contestants are split into pairs and battle it out head-to-head for a place in the final. Inspired by their time at the two Michelin-starred The Dining Room at Watley Manor, the chefs must put everything they've learned into preparing two courses in their sudden death cook-off. Only one chef can become a finalist - the other will be going home. The final two remaining semi-finalists must cook a busy lunch service at the two Michelin-star The Ledbury under acclaimed Australian-born Chef Brett Graham. They have only two hours to perfect Brett's dishes before preparing them for paying customers and possible Michelin inspectors. Once they have finished service, the two chefs must face another challenge: they must recreate Brett's Michelin-starred signature dish for judgement by the chef himself. Then it's back to the Masterchef HQ where the two chefs face a sudden death cook-off when they have to create two perfect dishes in one hour to show Michel and Gregg exactly what they have learnt. At the end of it one chef will be going home, leaving three finalists to prepare for the final week of competition.
