The teams are challenged to recreate Benoit Blin's Le Café Crème, a dessert he has made at Le Manoir aux Quat'Saisons for the past 30 years. But to make it even harder, they have no recipe to follow. After this, they create a deceptive gardening-themed illusion showpiece that hides a vegetable cake-inspired dessert to serve 24. Liam Charles and Ellie Taylor follow their progress.
