When it comes to afternoon tea, the British like nothing more than a sweet treat to go with it. The Hairy Bikers, Dave and Si, set off for the Henley Royal Regatta, and on their journey they fill their hampers with cakes and treats made along the way. But why do the British have such a love affair with teatime treats? In their quest to find out, Dave and Si stop off at a swanky hotel to examine the history and conventions of tea, where they are forced to don suits. Next, the Hairies make Bakewell Tart in the Original Bakewell Pudding Shop in Derbyshire, before travelling back in time on a pair of priceless Brough Superior motorbikes. They arrive at Chatsworth House and bake scones with maple syrup and buttermilk. In search of hints and tips on how to make the perfect Victoria sandwich, the boys visit the WI and cook their own version, but will it satisfy the judges' criteria? Finally, the boys hit Henley and cook chewy posh cookies with sour cherries and chocolate chips. They serve afternoon tea to the rowers from Tees Rowing Club, before taking to the water themselves.
