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 10 competing bakers 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.
