For most of human history, people were locked in a continual struggle to find food and avoid starvation. Eating for pleasure wasn't really a thing the common person could do. However, as time went on and technology improved, eating became as much a recreation as a hobby -- and this led civilization to the fascinating, ridiculous world of artificial flavors. In the first part of this week's special two-part episode, Ben, Noel and Max explore the science of flavor, and use the story of vanilla as a way to understand the problems that led to synthetic flavoring in the first place.
