Six new teams are thrown in at the deep end, with a secret challenge: to make a classic coffee éclair, accompanied by an amenity. They must draw on all their knowledge and experience as they have no recipe to follow. In their second challenge, the teams play illusionists as they create a Trompe l'oeil showpiece sculpture inspired by everyday household objects, within which a tarte Tatin to serve 40 must be hidden. Whose patisserie prowess will shine through?
