Episode 17

The best eight remain semi-finalists take on a daunting Invention Test in which they must create a dish inspired by the chicken or the egg. The MasterChef market is open, and with a larder full of ingredients to choose from, they must create a dish worthy of being put through to the next round. Two contestants will be eliminated at the end of this task.

The six survivors then travel to Middle Temple in central London, where a very special centenary event is taking place. The Royal British Legion is celebrating 100 years since the nation's collective remembrance traditions were first bought together and the organisation began its important work supporting serving and ex-serving personnel and their families. The poppy appeal, the two-minute silence, Armistice Day, the service for the unknown warrior and the march past at the Cenotaph are traditions that millions participate in every year. Under the supervision of Glynn Purnell, head chef of Michelin-starred Purnell's restaurant in Birmingham, the contestants are split into teams of two to deliver a three-course menu for a prestigious lunch celebrating over 20 war veterans and crucial fundraisers - all of whom have bravely served their country - so expectations are high.
