The last semi-final challenge is a celebration of MasterChef's surprise musical fame. Ten years after MasterChef judges John Torode and Gregg Wallace were sampled on the hit single Buttery Biscuit Bass, this episode marks this momentous achievement by returning the favour. The final six contestants must prepare a dish that is inspired by that song and one of over 20 different food references within it. Savoury or sweet, it's up to the contestants to interpret the brief, and the dish must impress the judges enough to secure a place in finals week. At the end of this challenge, one contestant's MasterChef dreams will be dashed, while the other five move closer to becoming MasterChef champion.

In the penultimate episode, the four remaining contenders face a single cooking task to earn a place in the final three and an opportunity to take part in a challenge of a lifetime. They are asked to prepare their interpretation of a classic dish that will showcase their growing cooking talent to judges John Torode and Gregg Wallace. It's their last chance to bring together everything they have learned, to let their creativity fly and to prove they are worthy finalists. This high-pressure cook-off will be the end of the journey for one of the four finalists.

For the three that remain, there is the dream chance to work with one of the world's greatest chefs in the toughest and most daunting challenge of the competition, the Chef's Table. This year, it's hosted at Restaurant Gordon Ramsay in London, by Gordon Ramsay himself. It's a special anniversary for the restaurant as it celebrates 21 years of holding an incredible three Michelin stars. The three finalists must work harder than ever to deliver food of an exceptional standard and impress some of the best chefs in the country. Dining are members of Gordon Ramsay's original brigade who have gone on to achieve culinary fame themselves, including Clare Smyth and Paul Ainsworth, as well as his old mentor, former three-star Michelin legend Pierre Koffman. Gordon, along with his head chef Matt Abé, put the finalists through their paces as they try to master Restaurant Gordon Ramsay's classic dishes. Can these amateur cooks hold their nerve, or is the pressure to deliver too intense?
