Can you expand on this? I've never heard of alkalized cocoa mass. Interesting... Cocoa mass is chrushed cocoa beans.. the crushing releases the cocoa butter in it. Cocoa powder is obtained by squeezing this cocoa mass and removing the cocoa butter. For chocolates they dont do that (not always), they only need to add more sugar, milk powder and a few other indgredients. The cocoa mass is sterilized using steam at a particular pressure and temp usually 120 deg C, if the steam used here has a alkaline added to it, its alkalized cocoa mass from which alkalized cocoa powder is pressed. I was fortunate enough to spend a month as a intern in a chocolate factory.
