Episode 23

It's finals week as the MasterChef anniversary celebrations continue, and two incredible challenges await our final four. They will have to give it their all, as at the end, John and Gregg will pick the three lucky cooks to move ahead to the grand final, where the 20th MasterChef champion will be chosen.

Things kick off in the exclusive London district of Mayfair. The fabulous four are about to get an experience that no amateur will ever get the chance to tackle again. This year marks the closure of Le Gavroche, one of the world's most celebrated restaurants, which has been at the forefront of gastronomy for the last 35 years. The brainchild of the Roux culinary dynasty, Le Gavroche was the first restaurant in the UK to be awarded three Michelin stars. The finalists will have the honour of taking charge of one of the last ever restaurant services, guided by Michel Roux Jr. himself. They will each cook one of the restaurant's classic dishes which catapulted it to stardom. If that's not demanding enough, they will be serving these dishes to a dining room that includes revered chefs who have also grafted in this very kitchen, including legendary three-star chef Pierre Koffmann, MasterChef's own Monica Galetti and Michel Roux Jr's daughter, Emily. They know the standards expected and will be hoping the finalists deliver a stunning menu befitting of this iconic restaurant before it closes its doors forever.

It's then back to the MasterChef kitchen, where just one challenge separates the contenders from this year's final. John and Gregg will be looking for them to deliver one exceptional plate of food that has special meaning, relates to something or someone they love and comes straight from the heart. This is for a place in the final three, so nothing short of spectacular will do the trick.

At the end, our grand finalists will be chosen, each of whom will be within touching distance of this year's trophy.
