Episode 2
Judges Benoit and Cherish want more miniatures - 36 uniform eclairs and 36 identical mont blancs. For their showpiece, the teams are tasked with making arguably the most important cake of one's life - a gateau de mariage. But when the final points are tallied, one team will have to leave.
Episode 3
For their miniatures challenge, they face the juggling act of making 72 perfectly baked viennoiseries with an added bicolour element as well as 72 tantalising cup petits fours. For their next challenge, they're given four hours to produce a magnificent under-the-sea themed chocolate showpiece accompanied by three types of chocolate bon bons, 108 in total.

The toughest bake off on television welcomes five new teams who, over the next three heats, battle it out for the last two semi-final places.
