It’s week four of and the remaining five bakers have travelled to Bakewell in Derbyshire. This time the bakers are reinventing an often neglected British classic – the pudding. There will be sticky toffee puds, peach and blueberry ”boy-bait’, rhubarb and orange betty and a cherry queen of puddings. But the surprise bake set by judges Paul Hollywood and Mary Berry really tests the baker’s ability to cope with the pressure. Will the bakers rise to the occasion? As the puds go in the oven, Mel and Sue roam the country finding out how and why puddings changed from ‘meat’ to ‘sweet’, visiting the birthplace of school puddings and discovering how puddings helped change Britain’s image overseas.
