Why measuring unsweetened cocoa powder by cup goes wrong
Cocoa powder is roasted, ground, defatted cacao. A cup weighs about 85 grams — light by volume because cocoa is fluffy and air-trapped. Natural cocoa is acidic (pH 5); Dutch-processed (alkalized) cocoa is neutral (pH 7). They are not interchangeable when a recipe uses baking soda alone — the soda needs the acid in natural cocoa to leaven properly.
Practical tips for working with unsweetened cocoa powder
Sift cocoa powder before adding it to a batter. The small clumps that look like nothing in the bag streak through a cake batter and bake into bitter dark specks. If a recipe doesn't specify natural vs. Dutch, the safe assumption for American recipes is natural; for European recipes, Dutch.
Note from this ingredient's record: Natural and Dutch-processed weigh the same per cup but behave differently with leaveners — Dutch is alkalized and is not activated by baking soda alone.
