Understanding your chocolate from tree to tummy is one of the most important things you can do to make healthier, more ethical chocolate choices. During this session at Loncon 3 the World Science Fiction Fantasy Convention's return to London after more than 50 years, I explained how cocoa grows, where it grows, the different types of cocoa, how it is harvested, fermented and dried then about the roasting, winnowing, refining and conching that is all required to make awesome chocolate. Once we learned about it, we got to try SEVEN awesome chocolates from FIVE amazing suppliers!
