Overview: John Torode and Gregg Wallace are looking for the country's next star chef. In this double-length episode comprising a heat and quarter-final, contestants will face three high-pressure tests: inventing a dish from scratch, cooking at Las Iguanas and creating a two course meal to impress the judges. Those who make it through to the quarter-final must prove their knowledge and passion for food. The heats have produced four exceptional cooks, but only one of them will make it through today to become a semi-finalist.
