Black Onyx Cocoa Powder
This cocoa powder has been alkalized to the extreme, producing a dark, purplish black cocoa that makes for an impressive black-as-coal baked good. This extreme alkalization neutralizes the natural bitterness, removing some of its chocolate flavor and a lot of its butter fat (10-12%).
We recommend replacing 25-50% of the standard "Dutch" cocoa in a recipe with black onyx. Using this ratio will produce darker, rich tasting baked goods without losing the moisture. If needed, you can increase the fat content by adding more butter, egg yolk or changing to a heavier milk; whichever applies to your particular recipe.
