The contestants are tasked with cooking a three-course fish lunch for some of the country's biggest fish experts. Starting at 4am at Billingsgate Fish Market, they must first source their ingredients before moving on to Fishmongers' Hall, the prestigious headquarters of the Fishmongers' Company, where they take full control of the kitchens. John Torode oversees the kitchen as the amateurs face a high-pressure lunchtime service. The contestants must each serve one dish of their own creation on the specially designed menu, and the two chefs who cook the most popular dishes will be exempt from the next cook-off. Back at the MasterChef kitchen, the MasterChef market reopens as the five chefs cook against each other in a bid to stay in the competition, and this time there is no meat or fish. They have one hour and fifteen minutes to create one dish to keep themselves in the competition.
