This time, judges Cherish Finden and Benoit Blin set the teams two tricky challenges. The first one requires two batches of perfectly uniform miniature classics - 24 gateaux Basques and 24 tartes Tatin, in just three and a half hours. For the showpiece challenge, the teams have five hours to reinvent a classic dessert. The dessert is the Battenberg, with teams striving to create an extraordinary version of this teatime favourite.
