PREVIEW: The Secret World Of Biscuits, Channel 4

Dawn French narrates this behind-the-scenes look at Britain's biggest snack rivalries, with this nostalgically sweet, and perhaps a little unsavoury, story of the battle of Britain's biscuits.



From Penguins and Clubs to Hob Nobs and Jaffa Cakes, the biscuit world has seen copycats, high court battles and cost-cutting. It's a brutal world where eight out of ten new products fail.


This episode reveals how industry heavyweights are unwrapping the secrets of keeping biscuits ahead of the pack.


Airs Sunday at 8pm on Channel 4.
