Natural cocoa powder is quite strong and has the flavor of rich, dark chocolate. Natural cocoa powder comes from pressing cocoa beans with no additional modifications. The resulting natural cocoa powder is usually a light brown color. It is used in baking (this is the type of cocoa most recipes call for).
Spice Fun Fact: Cocoa is called cocoa and not cacao due to a spelling mistake made by English importers during the 18th century when chocolate was becoming popular.
