Chocolate
Cocoa powder is the pulverized cocoa solids left after extracting almost all the cocoa butter. It is used to add chocolate flavour in baking, and for making chocolate drinks. There are two types of unsweetened cocoa powder: natural cocoa produced by the Broma process, with no additives, and Dutch process cocoa, which is additionally processed with alkali to neutralize its natural acidity. Natural cocoa is light in colour and somewhat acidic, and is commonly used in recipes that also use baking soda; as baking soda is an alkali, combining it with natural cocoa creates a leavening action that allows the batter to rise during baking. Dutch cocoa is slightly milder in taste, with a darker colour. It is frequently used for chocolate drinks such as hot chocolate due to its ease in blending with liquids. However, Dutch processing destroys most of the flavonoids present in cocoa.
