The first time I visited the place where the company I was working for made their own chocolate, was blown away by the massive blocks, about half my height, of what looked like chocolate. And then someone suggested I taste a little bit.
Extremely bitter and almost nothing like the chocolate that you and I know and love, I couldn’t believe I’d been tricked. What I was actually tasting was cocoa mass which is produced from fermented and crushed up cocoa beans. Chocolate manufacturers add sugar (and for milk chocolate some milk powder) to the cocoa mass to make chocolate.
If you ever come across a 99% cocoa chocolate, give it a try. You probably won’t like it that much but it will give you an idea of what chocolate tastes like without the sugar.
