The confusion fusion that is Sweet & Sour sauce! We learn how it became a Chinatown staple and racist immigration policies of the US from the 19th century. It's crazy. We meet Robert C. Baker the hero who invented the chicken nugget. Guess how much money he made off of that venture? It's a stunner. Emily shows off her knowledge as an unofficial McDonald's historian. We tour (via an article) the zero-rated restaurants in Swindon. Disclaimer: This is not a vegetarian friendly episode.
