It is the penultimate test for the three Masterchef finalists. The contestants face two daunting challenges - cooking a 60,000 pounds three-course dinner for 200 specially invited guests at the opening night of the world famous Burghley Horse Trials. Then they have to cook for eight of the world's best chefs who hold 16 Michelin stars between them. Guests include the GB Olympic team and World Eventing Champion Zara Phillips.
