We visit Warburtons to see how they produce 36,000 crumpets an hour. The company is the UK's largest crumpet producer and Europe's largest bakery, producing around 800,000 packets of crumpets a year. We took a tour of the factory to see how the popular British cuisine is made. Is it bread? Is it a pancake? Is toast? Watch the making of process to see what goes into these spongy breakfast treats.
