Liam Charles and Ellie Taylor present as the best three teams from each set of heats come together. They start off with another secret challenge - six identical plant-based petit gâteaux that feature both chocolate and blood orange, with no recipe to hand. The baking wizards and witches then have to defy gravity as they produce hanging showpieces made entirely from chocolate, delicately suspended from the ceiling, and with two batches of macarons sitting within. Benoit Blin and Cherish Finden decide which pair have to go.
