This quarter-final sees four chefs presented with an Invention Test, in which Marcus Wareing and Monica Galetti taks them to create a dish based on the set theme of cheese. They are presented with an abundance of potential ingredients, including an eclectic range of cheeses from around the world, and afforded 10 minutes to select what they need and 70 minutes to prepare and serve their dish. They are then tasked to offer a stand-out two-course menu for leading restaurant critics Tracey MacLeod, Jimi Famurewa and Jay Rayner. Only the most talented chefs will then go forward to the semi-final stage.
