Double-Michelin-starred chef Michel Roux Jnr and MasterChef dining expert Gregg Wallace ask the last pair of semi-finalists to step up to service at Pied a Terre. Working under head chef Marcus Eaves, they must now compete in the heat of service and reach the exacting standards of Michelin star cuisine. They will each be responsible for a highly complex dish that must be executed with precision, finesse, and on time. No mistakes will be tolerated. Then, after a relentless service the chefs must compete again recreating one of Marcus's signature dishes: poached lobster with crushed peas, confit white peach and a mint and tarragon emulsion. To bring together such a delicate balance of flavour, it's a battle for the chefs to reach the extraordinary level required. Then, the two semi-finalists return to the studio for one last challenge before one of them will be sent home. In this daunting final test, they must produce a main and dessert inspired by their Michelin experience in just two hours - they simply have to electrify the judges with their cooking. Any mistake could cost them the competition so with the pressure firmly on, it is a tense and thrilling battle. Once Michel and Gregg have judged their two courses, they must decide which chef will leave the competition. At the end, only the very best chef will win a place in the finals and have the chance to become this year's champion.
