It is week three of the competition and the six remaining bakers are making bread in Kent. If they found cakes and biscuits challenging, it's bread that's considered the real test of a baker's mettle. In the shadow of Sarre Windmill, the bakers will be kneading, proving and knocking back their dough under the watchful eye of baking writer Mary Berry and master baker Paul Hollywood. And as they battle it out to produce the perfect loaf, Mel and Sue will be tasting Britain's earliest bread roll, finding out what happened to bread during the Industrial Revolution and relating the hidden history of the sandwich. Making bread is an ancient skill. Which of the bakers will best cope with the pressure and who will be the one who has to leave the Bake Off?
