MasterChef

It's quarter-final time, and the six cooks who have already shown their potential this week are back to fight for their place in the competition. Success will mean a place in knockout week, so it's all to play for. The brief is set by the formidable Jay Rayner, who would like each of the cooks to make a wrap. Tortillas, spring rolls, burritos and flatbreads are just some of the ideas that might come to mind. They can fill their wrap with ingredients of their choosing, but whatever wrapper they decide on will also need to be made from scratch - this is MasterChef after all. They have 90 minutes - time to create something truly delicious, but also enough to make mistakes. A spot in knockout week will be given to those who impress the judges the most.
