Am making the Chocolate Sugar cookie recipe from Cook's country (April 2013) and need 3/4 cup unsweetened cocoa powder. I noticed I had 2 of them, Ghiardelli's and Scharffen Berger. Both just say cocoa for ingredients. They look very different, one is much darker than the other. And stranger, the Scharffen Berger suggests 3 tab cocoa plus 1 tab sugar per 8 oz cocoa drink and the Ghiardelli suggests 1.5 tab each cocoa and sugar per 8 oz. Are they different strengths or just different tastes? Does anyone have a favorite unsweetened cocoa powder?
