In the city of Lyon, France's chocolate and gastronomy capital, techniques are a well-kept secret. Philippe Bernachon shows us part of the process of making chocolate from cocoa beans. At the Voisin chocolate factory, we learn about how to make old-fashioned pralines from huge slabs of chocolate. Meanwhile, Willy Ferrier tells us about his unique work as a chocolate sculptor.
