MasterChef judges John Torode and Gregg Wallace set a truly daunting challenge for the contestants as they continue their search for this year's best amateur cook. The remaining 12 amateur cooks have a baptism of fire as they face each other in the MasterChef kitchen for the first time. Not only do they have to be at the top of their game to ensure good food on time, but their guests for this pressure cooker of a challenge are a group of people who know exactly how high the MasterChef standards are - a selection of previous MasterChef winners and some of last year's finalists.
