John Torode and Gregg Wallace are looking for the country's next star chef. Six contestants, picked from thousands of hopeful amateurs, will face three high-pressure tests. First they have to invent a dish from scratch in 50 minutes, using only the ingredients they've been given. Next, the three contestants who've shown the most potential will have to survive the heat of the professional kitchen at Delfina. Finally, they will have to impress the judges with a two course meal that shows they have flair, skill and the potential to make it as a great chef. Only one of them will get through to the quarter-final.
