‘The internet… pah!’ says historian Ruth Goodman, trying to convey how massively steam engines changed our lives. And when it comes to food – today’s theme – she’s clearly not exaggerating. Before the railways, traction engines and the steam plough, people ate food produced locally and that was that. After their arrival, Scottish beef, Somerset cider and Yorkshire rhubarb could not only be rushed to every corner of the nation, but the very existence of the railways allowed these regional specialisations to develop in the first place. So steam hasn’t just made the world a modern, faster place, but a tastier one, too!
