There are 3 different types of chocolate - milk chocolate, dark chocolate and white chocolate. Milk Chocolate - It is the most widely distributed type of chocolate. It contains milk, cocoa and sugar. The percentage of cocoa and milk differs from region to region. Dark chocolate - Dark chocolate is the closest form to pure cocoa, which tastes slightly bitter. This kind of chocolate is also used for preparing desserts and cakes. White Chocolate - This kind of chocolate contains a significant amount of milk and added sugar. It only contains cocoa butter, which gives the chocolate bar its white colour.
