Inside the Factory: Potato Waffles

Gregg Wallace is in Lowestoft, at an enormous factory where they produce 450 tonnes of frozen food each day. He follows the production of frozen potato waffles, from the arrival of 25 tonnes of spuds right through to dispatch. Meanwhile, Cherry Healey learns about the difference between waxy and floury potatoes and finding out which spud should be used for which job. And Ruth Goodman is myth-busting Walter Raleigh's connection to potatoes. She discovers he couldn't have brought them back from North America, because there weren't potatoes there until 20 years after he died
