It's the last of the semi-finals, and the remaining six celebrity cooks continue to battle for the MasterChef title. Their first task is the Great Classic Dish Test. Each of the six benches in the MasterChef kitchen contains the ingredients and recipe to make a different classic dish from around the world, including chicken kiev, a Portuguese fish stew, lamb koftas and queen of puddings. To stay in the competition, the celebrities must pick a bench at random and then perfectly cook the dish that's on it. Next, the remaining five celebrities face their most daunting challenge yet - to prepare a five-course dinner for the Chelsea Pensioners in celebration of HM the Queen's 90th birthday. However, they won't be cooking their own dishes. They will be cooking the menu of one the country's greatest chefs - Nigel Haworth of Michelin-starred Northcote Manor. Under his guidance, and following a recipe, they will each have to recreate one of his dishes, but to succeed they will have to master ideas and techniques they could never have imagined. Finally it's back to the MasterChef kitchen, where the final five must each create one exceptional dish that celebrates the life of someone important to them. The celebrities must impress John and Gregg by showing that they can put passion into their dishes and have the heart and determination to remain in the competition. The greatest cooks in the world are able to show emotion through their food - will our remaining cooks be able to do the same?
