Overview: It is the quarter-final, 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. Today's brief has been set by food critic William Sitwell, and the contestants must cook either a savoury dish that has no meat or fish, or a tart dessert. After cooking their dish, the contestants must stand before William Sitwell, John and Gregg to hear what they think of their dish and how well they have kept to the brief. At the end of the quarter-final, the best cooks are put through to Knockout Week, taking them another step closer to being crowned MasterChef Champion 2017.
