The semi-finals continue with only the eight best chefs left standing. They are now split into two groups and over the next two nights will strive to secure an all-important place in Finals Week.

Tonight, the first four face two challenges, beginning with their first task outside the MasterChef kitchen. The MasterChef: The Professionals pop-up opens its doors in a warehouse microbrewery in industrial east London.

In recent years, pop-up restaurants have revolutionised the way we eat. With a vibrant mix of cuisines on offer in dynamic settings, some of the most exciting food currently in the UK has come from the pop-up industry, enabling creative chefs to make a name for themselves without the costs of opening a traditional restaurant.

The semi-finalists have an opportunity to make an impression in this vibrant world as they cook their own dish for 20 of the UK's top pop-up chefs and entrepreneurs. They each have three hours to deliver a dish designed to get this influential crowd talking, but with makeshift workstations, limited equipment and no ovens, who will be able to adapt their fine-dining style and serve up a dish that says star quality?

For the second task, the four chefs return to the MasterChef kitchen and have one hour and 45 minutes to cook their own Desert Island Dish – a dish they would take with them if they were stranded on a desert island. With places in Finals Week at stake, the slightest mistake could mean they miss out on the chance of a lifetime.

Once Marcus, Anna and Gregg have tasted all the dishes, it will be end of the road for one chef, while the best three go through to Finals Week and stay in the running for the MasterChef: The Professionals 2022 title.

It's Finals Week, and only the six most exceptional chefs are left standing. Tonight, six become four as they battle for the once-in-a-lifetime opportunity to cook their food for a dining room full of culinary legends at the Chef's Table.

First, the contenders must cook off against each other in the MasterChef kitchen to prove they are worthy of cooking at this incredible event. They have one hour and 45 minutes to pull out all the stops and cook a dish that showcases their best culinary attributes and technical abilities. Each must draw on all their knowledge and skill to create a stunning plate of food that shines out in a room full of talented chefs. At the end of this challenge, the judges will decide which four can continue in the competition.

The Chef's Table is one of the most prestigious events in the British culinary calendar, and this year it's being held at the five-star Lanesborough Hotel in London. For the remaining finalists, it's a unique chance to prove their talent to 20 of their professional heroes, who hold 19 Michelin stars between them. They include Matt Abé (3* Restaurant Gordon Ramsay), Nieves Barragan Mohacho (Sabor 1*), Lisa Goodwin-Allen (1* Northcote), Jason Atherton (The Social Company 3*) and the much-loved MasterChef judge and renowned chef patron of Mere, Monica Galetti.

Cooking for these culinary giants is a huge honour, and the chefs have five hours to prepare one course each for this unique dinner. The pressure is on to execute every single element to perfection and send 20 identical, exquisitely presented dishes out to the guests. Nothing can go amiss as the expert diners will be seeking flawless, mouthwatering, original food. For the finalists, these dishes could make or break their careers and their chances of winning the MasterChef: The Professionals 2022 title.
