What does the percentage mean?
The higher the percentage, the more bitter the chocolate. That’s why unsweetened chocolate, a.k.a. bitter chocolate, which contains 100 percent cocoa bean product, is only suitable for baking. Semisweet chocolate has at least 35 percent cacao, but usually around 55 percent, with added sugar, but no dairy. Milk chocolate only has to have 10 percent cacao at minimum and 12 percent milk solids. This gives it a creamy, rich taste, but all the added sugar makes it much sweeter too.
