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 face three tests: inventing a dish from scratch, cooking at Zilli Fish and creating a two-course meal to impress the judges. Those who make it through to the quarter-final must prove their knowledge of- and passion for food. The heats have produced four exceptional cooks, but only one will make it through to become a semi-finalist.
