Step inside the chocolate factory to hear the secrets of what it’s like to invent sweet treats for a living.

Find out why chocolatiers think the raw material is like a “needy child”, but can also bring great joy to people’s lives.

And hear the family story of the invention of one of the best-known British chocolate bars, with a trip to an archive of hidden stories from the confectionary industry – and some well-preserved sweets.
