Dutch process cocoa powder (AKA "alkalized” or "European style” cocoa powder) is the smoother, more mellow alternative to natural cocoa powder. According to Serious Eats, the cocoa beans are “washed with a potassium carbonate solution that neutralizes cocoa's acidity to a pH of 7” (this is known as the “Dutching” process). As for flavor, Dutch process cocoa is smooth, mild, and pure in chocolate flavor. It’s the perfect choice in chocolate-forward recipes like this hot chocolate.
