The first heats continue as the four remaining celebrities face three more culinary challenges, competing for a place in the semi-finals.

Their first challenge is a knowledge and skills test. They have the terrifying task of facing judges John Torode and Gregg Wallace one by one to demonstrate their ability to identify a tray of ingredients, four types of biscuit and four creams, before being asked to make a filled brandy snap from scratch in just 15 minutes.

Then the celebrities are paired into teams and sent out on their first mass catering challenge. The celebrities must provide lunch for over 100 members of staff at the London Central Mail Centre, Royal Mail's largest sorting office. With an array of ingredients including chicken breast, diced beef, kidneys and a range of fruit and vegetables the two teams must devise, prepare and serve the lunch catering for various tastes while creating meat-based, vegetarian and dessert dishes in volume.

Then it's back to MasterChef headquarters as the battle for a semi-final place reaches its climax. The four celebrities must now cook a faultless two-course meal that will not only be judged by John and Gregg but also past Celebrity MasterChef champions, author Emma Kennedy and former England rugby captain Phil Vickery, and previous finalist Andi Peters, who know exactly what standards they expect.

With their last chances to impress for a semi-final place, emotions in the kitchen are running high and the pressure proves too much for some contestants. The celebrity judges deliver some frank and cutting responses to some of the dishes, but others fare much better.

Only the best two contestants can earn a semi-final place and become a step closer to winning the title of Celebrity MasterChef 2014.
