It's the second quarter-final of the series and the four talented heat winners have no time to rest on their laurels as they continue to fight for their place in the competition.

The week's best amateurs are put through the mill with a seriously daunting test - the critic's brief. The home cooks have to impress just one food critic with two dishes. They are given the critic's brief and must create a main and a pudding based on it.

Tonight's brief has been set by the respected and discerning Tracey MacLeod, who asks them to cook a main course based on the following instruction: 'I am looking for a cook who can successfully create an all-vegetable or a vegetable-led dish where it is the main player - it doesn't mean it has to be vegetarian, the vegetable just has to be the star.'

After cooking their savoury dish based on this brief, but without knowing who has set it, the contestants are finally introduced to their critic and must stand before them with their dish. Face to face, they will hear exactly what Tracey MacLeod, as well as John and Gregg, thinks of the main and how well they have kept to the brief.

After this searing honesty, the quarter-finalists must return to the kitchen and prepare a dessert that fulfills Jay's brief - 'fruit and spice, and all things nice.'

At the end of tonight's quarter-final, three cooks will go through to Knockout Week, taking another step closer to being crowned MasterChef Champion 2015. For one, their MasterChef dream will be over.
