It's the last quarter-final of the heats and the six talented heat winners have no time to rest on their laurels as they continue to fight for their place in the competition - and a place in knockout week. The week's best amateurs will be put through the mill with a seriously daunting test set by one of the country's toughest food critics. Tonight's brief has been set by Jay Rayner. His challenge is for the amateur cooks to make an exceptional dish centered on one ingredient - duck breast. After cooking their dish based on this brief, the contestants must stand before Jay Rayner and John and Gregg, and hear what they think of their dish and how well they have kept to the brief. At the end of tonight's quarter-final, the best cooks will go through to knockout week, taking another step closer to being crowned MasterChef Champion 2016.
