It's the last week of the heats and the final group of amateurs battle for a place in the quarter final. Five more hopefuls try to prove to judges John Torode and Gregg Wallace that they have the potential to be the 2016 MasterChef Champion. Firstly they are asked to cook their Calling Card, a dish that represents who they are as a cook. After tasting all five dishes, John and Gregg each pick their favourite dish. If they both choose the same dish, then they will select their second preference. The two lucky cooks will sail straight through to the second test. The remaining three contestants are presented with two trays - one contains the ingredients for a sweet dish, the other has ingredients for a savoury dish. The contestants must decide whether to create a savoury dish using lamb rump as the main ingredient or a sweet dish using mango as the central ingredient. Once they've made their decision, they have one hour to create a dish that will impress the judges and earn them a place in the next round. The stakes are high as after this cook-off, one of the amateurs will be sent home. The four remaining cooks now have to cook two courses that will excite not just John and Gregg, but also some very special guests. Some of MasterChef's most inspiring winners and finalists return to judge the food of this year's new contenders. The contestants must attempt to impress 2014 finalist Luke Owen, 2014 finalist Angela Langford and 2014 champion Ping Coombes. John and Gregg will then decide which three contestants deserve to go through to Friday's quarter final.
