Marcus Wareing, Monica Galetti and Gregg Wallace team up to search for the country's next culinary superstar. Six new chefs compete for a place in the quarter-finals. The first three chefs begin with a skills test set by Monica. They have 15 minutes to make a sea bass ceviche. The remaining three chefs must complete a skills test set by Marcus, who examines their butchery skills and subtlety of flavour, when they are asked to cook a pork chop and grain mustard sauce. In the final challenge, the six chefs come together to cook their own signature dishes.

Marcus Wareing, Monica Galetti and Gregg Wallace team up to search for the country's next culinary superstar. It is the quarter-final and the six best chefs from the week's heats return to the MasterChef kitchen to continue in the pursuit of the winner's crown. Monica and Marcus ask the chefs to reinvent and reimagine a great family favourite - fish and chips. They will need to elevate the dish to a new standard without losing its heart and soul. Next, the chefs cook for some of country's most discerning restaurant critics. This week's food critics are Jay Rayner and William Sitwell, joined by Amol Rajan, editor at large of The Independent, who is not bashful about bringing his opinion to bear.
