To dunk or not to dunk, that is the question!

Join Heston, his long time TV producer Jay and Fat Duck Producer James as they travel inside the wonderful world of biscuits.  

What is the best dunker?  Which is the oldest biscuit in Britain?  How do you make the perfect biscuit?  What odour molecules are released when we eat biscuits that make us love them so much?  And why do us Brits love a dunk?   

All this and more as Heston journeys to the centre of the biscuit.
