It is semi-final week for the remaining contestants, who know they are just three patisserie challenges away from the biggest day in their baking lives. First comes the Signature and a deceptively simple challenge, with Paul Hollywood and Prue Leith looking for perfection, followed by Prue's complex, multi-layered Technical. The pressure intensifies when they are asked to create a spectacular Showstopper that could grace a Parisian patisserie - but who has the skill to reach the Bake Off final and who will fall at the final hurdle?

The Great British Bake Off Show Summary

The Great British Bake Off sees ten passionate home bakers take part in a bake-off to test every aspect of their baking skills as they battle to be crowned the Great British Bake Off's best amateur baker. Each week the nationwide tour sees keen bakers put through three challenges in a particular discipline.

The competition kicks off with cake in the Cotswolds, then moves to Scotland to tackle biscuit baking, then Sandwich in Kent for bread, Bakewell in Derbyshire for puddings, Mousehole in Cornwall for the pastry challenges, and London for the grand final.

Judging the baking are renowned baking writer Mary Berry and professional baker Paul Hollywood; presenting the show are Mel Giedroyc and Sue Perkins, who trace the very particular history of British baking by visiting local baking landmarks and discovering why people bake what they bake today.
