John Torode and Gregg Wallace return with the cookery competition, as a new batch of contestants are put through gruelling culinary challenges to test not just their skills, but also their knowledge of food and ability to cope in a professional kitchen. This year they will have to cook not only for their place in the competition but also the right to wear a coveted MasterChef apron, with six contestants in each heat and only four aprons up for grabs, beginning by preparing their signature dish.
