Making chocolate may look simple. After all, you only need a few ingredients: cacao beans, sugar, and milk. Yet mixing them correctly to achieve a smooth, velvety texture took centuries to achieve. And it's all thanks to Swiss chocolate makers.
They were the first ones to achieve a smooth, sweet, creamy chocolate. But, most importantly, they invented the conching machine, the most important machine in making chocolate. We visited Favarger in Geneva, Switzerland, for a tour of its chocolate factory.
