The Great British Bake Off

With the cake week completed, and one of their number already eliminated from the competition, the 11 remaining home bakers must now prove their skill at making biscuits, a task that can be deceptively difficult, and one that has undone many a confident Bake Off contestant in the past. The opening signature challenge this week is to create 24 biscotti, Italian delicacies that must be baked twice to deliver the perfect crisp crunch. Next is Paul Hollywood's technical challenge, in which the contestants tackle Arlettes - labour-intensive, puff pastry-based treats from southwest France. Finally, for the showstopper, the judges demand bespoke edible biscuit boxes, filled with 36 biscuits of different flavours. After all three rounds have concluded, it falls to Mel Giedroyc and Sue Perkins to announce which of the bakers will be asked to leave the tent
