The semi-finals are under way, and the six chefs left standing return for the chance to impress one of two rising culinary stars, before battling for a place in the final five.First up is a visit from groundbreaking chef Victor Garvey, a native New Yorker who has set today's brief. Victor has worked to redefine modern American food from his Michelin-starred restaurant SoLa, in London. His dishes are inspired by his memories growing up, and the main aim is to create familiar, but surprising, plates of food. Today, it's down to the contestants to raid their memory banks and each deliver two bite-sized snacks that hit his standard. Not only that, their challenge will also be run as a restaurant service, with an hour to prep and cook, and 30 minutes to finesse and plate. This is no small feat.The theme of special memories continues into the next task. All six will need to deliver a dish that brings back thoughts of a special occasion. Inspiration can come from anywhere - the perfect Christmas, a romantic first date, a birthday lunch – but all that emotion must be represented in the plate of food they serve the judges.For one chef, the competition will be over, leaving just five still in with a shot at becoming MasterChef: The Professionals champion 2024.
