Cocoa powder is produced from slabs of roasted cocoa bean particles that are left behind when cocoa butter is extracted. Since pressing does not remove all the cocoa butter, so the particles remain coated with a thin layer of cocoa butter, the overall fat content of cocoa powder varies from 8% to 26%. These solid particles (cocoa powder) are the basis of the taste of chocolate. As a result, cocoa powder is the darkest version of chocolate ever.
