Tom Allen and Liam Charles present as the pastry chefs create miniature cone-shaped and carrot-shaped desserts - 24 of each. For the second challenge they must serve up a grand occasion showpiece - a Religieuse a l'Ancienne - to serve 24 people, with two different flavours of eclairs and inspired by the theme of time travel. Benoit Blin and Cherish Finden judge their efforts.
