Here are the basic blends of ingredients for the various types of chocolate:
Cocoa Butter – It is a pale-yellow, edible vegetable fat extracted from the cocoa bean, used to make chocolate. It has a cocoa flavor and aroma. Cocoa butter is a major ingredient in all types of chocolates. The more expensive chocolate (processed longer) have a smoother texture and mouthfeel.
Cocoa Liquor or Chocolate Liquor - It represent pure cocoa mass in liquid form. It contains cocoa solids and cocoa butter in roughly equal proportion.
Fat – Up to 50% of cocoa can be fat, comprised from two saturated fatty acids (palmitic and stearic acids) and one mono-unsaturated acid (oleic acid). This fat in cocoa butter and chocolate is not raising blood levels of cholesterol, however other ingredients in some chocolate products can cause that effects (milk, other forms of fat ingredients).

Fruits and Nuts - Used for specialty chocolates.
