The competition is switched up to high as we reach the first quarter-final, where this week's six most talented contestants return to cook off against each other for the first time. The judges know they can all deliver under pressure, but with only one task standing between them and a place in knockout week, every contestant will need to be on their A-game. A special occasion calls for a special guest. William Sitwell is on hand with a brief that will put the hopefuls through their paces. They will each need to use either a sweet ingredient in a savoury dish, or a savoury ingredient in a sweet dish. Nothing is off limits, but the result must be nothing short of delicious. They have 90 minutes to turn the culinary world on its head and show William why they made it this far. The best plates of food will secure the first spaces in knockout week, where the hard graft truly starts and the chance of becoming MasterChef Champion 2025 feels closer than ever.
