Overview: Heston celebrates the tea break by making the world's biggest packet of biscuits, the largest pyramid tea bag and a drink containing the flavours of cucumber sandwiches and Victoria sponge. Tea and biscuits are still a staple of the nation, with 185 million cups washed down every day and nearly 90% of tea drinkers liking to dunk. But the tea break itself has died a death. Heston wants to bring it back to life and takes on the challenge of creating a packet of biscuits big enough to feed a whole town - so he combines the chocolate Digestive, HobNob and Gingernut biscuit with salted caramel and pockets of chocolate ganache.
