This week's challenges test them on how they cope working with unconventional flours and unusual desserts which push their creativity to the max.

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.
