Here's a simple way to remember which one to use when baking.
"Dutched" cocoa differs from natural in that an alkaline solution is added to the beans during roasting, mellowing their acidity. Reddish brown and milder tasting than natural cocoa powder, Dutch process cocoa powder is ideal in baked goods where its subtle flavor complements the other ingredients. It should be combined with an acid such as baking powder.
Natural or American-StyleNatural cocoa powder is acidic, so must be combined with an alkaline ingredient such as baking soda to create bubbles of carbon dioxide, which cause leavening. With an intense, bitter, deep chocolate flavor, it tastes great in brownies and cookies.
Peace in the Kitchen!
