There are three challenges inspired by nature. The bakers can reach for anything that grows to give their bakes maximum botanical taste.
The bakers start with a signature challenge with a twist, that demands sharp citrus flavours and perfect peaks. Hidden under the gingham cloth is a leafy technical challenge set by Mr Hollywood. And finally, the botanical showstopper is the biggest challenge of the series so far - not one, not two, but three tiers of elaborately decorated cake.
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.
