Cocoa powder gives an intense chocolate taste and is available in “Dutch-processed” (alkalized) or natural varieties. Natural cocoa powder is light brown, with a strong, pronounced chocolate flavor.
It is slightly acidic, so it is best to use natural cocoa powder in recipes calling for baking soda. It is also used to make Hot Chocolate and no-bake cookies. Alkalized cocoa powder is darker in color, less acidic, and has a milder chocolate taste. Alkalized cocoa powder is recommended for recipes that call for baking powder.
