This week's seven remaining home cooks return to try to prove to judges John Torode and Gregg Wallace that they have the potential to be MasterChef champion 2022.

Tonight, the contestants face two more challenges that are designed to gauge both their creativity and culinary repertoire. The first is the Market Challenge, where the seven must invent a dish on the spot for judges John and Gregg from a market full of ingredients including poussin, clams and whole bream. At the end of this test, one contestant is sent home.

The remaining six take on their most demanding assignment so far - cooking a dish to a brief set by one of the country's toughest food critics, Jimi Famurewa. Jimi has asked them to cook a dish with an interactive, playful or theatrical element to surprise and delight him and the judges.

At the end of this episode, only four contestants can go through to this week's quarter-final. Who can handle the pressure and show they have what it takes to progress further in the competition?

It's the fourth week of heats, and nine talented home cooks arrive with both their dreams and ingredients ready for their first test, the Audition Round. Each must prepare a signature dish that shows judges John and Gregg who they are as a cook and how good they could become.

John and Gregg don't witness them cook in the MasterChef kitchen. Instead, they taste each dish in the new Tasting Room. Just like diners in a restaurant, they judge each contestant's food solely on the plate that is put in front of them. After tasting all nine plates, John and Gregg pick their three favourite dishes, awarding those cooks a MasterChef apron and immunity from cooking in the next round.

The remaining six contestants then get another chance to impress the judges and win themselves a coveted apron. If they delivered a savoury dish in the first round, they must now prepare a sweet, or vice versa. This time, John and Gregg are in the kitchen witnessing their every move. The pressure is intense and the stakes are high as only four cooks can join the three already fast-tracked in the next round of challenges. For the other two, their MasterChef dream will be over.
