Jo Brand tells the nostalgic story of how Britain fell in love with ice-cream, in an episode that peeks behind the curtain of the nation's favourite frozen treat. The heavyweights of the industry reveal the battles fought to dominate freezers, from the earliest innovations of Wall's and Lyons Maid, to the sophistication of Mars and the introduction of high-end luxury from Haagen-Dazs to Ben & Jerry's.
