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. In search of tips on how to make the perfect Victoria sandwich, the boys visit the WI and bake their own version, but will it satisfy the judges' criteria? Finally, the boys hit Henley and make 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.
