Inside The Factory | Preview (BBC Two)

In this episode of this new series of Inside the Factory, Gregg Wallace visits a Manchester factory that churns out 6 million Jaffa Cakes every single day.

Elsewhere in the episode, Cherry Healey visits the city responsible for growing the fruit that gives these cakes their name. The ancient port city of Jaffa, on the Mediterranean coast in Israel and the birthplace of the Jaffa orange. She also travels to the world marmalade making championships in Cumbria to get some tips from the reigning champion.

Historian Ruth Goodman investigates why a multimillion pound court case rocked the cake and biscuit world when an urgent legal decision was required as to whether this was a cake or a biscuit.

Inside The Factory returns Tuesday 4th April at 8pm on BBC Two.
