Inside the Factory: How Our Favourite Foods Are Made (BBC2, 8pm)

In this helping we go on a journey to assorted factories with Cherry Healey and the ubiquitous Gregg Wallace. They reveal how three of the nation’s favourite foods – bread, milk and chocolate – are produced. Plus, fresh from her series How Railways Made Britain, Ruth Goodman looks back on the history of these household staples. After an hour of watching this show, you may never look at those items in the same way again.
