After four weeks of intense competition eight exceptional celebrity cooks are left to fight for their place in the semi-finals as they try to impress judges John Torode and Gregg Wallace by cooking just one show-stopping dish in one and a half hours. Although it may seem like a simple task, a mistake in choice of dish or flavour combination could mean the end. They have to demonstrate a clear knowledge of their ingredients and showcase some of the skills they've learnt throughout the competition so far, but at the end of this challenge, two more celebrities will be going home.
Then, the six who have made the grade take a trip back in time when they must cater for the soldiers in the War of the Roses. One hundred members of a battle re-enactment society stage a battle in the grounds of historic Warwick Castle. Working in two teams they must create mouth-watering meals from a selection of ingredients that would have been available in medieval times including rabbit, pike and quinces.
