This is a recipe for a dark chocolate cake. It calls for 2 ounces unsweetened chocolate. But I made a mistake and bought the 70%. The recipe also calls for 1.25 cups sugar. I don't want it to be too sweet, so by how much should I decrease the sugar?
The last time I baked this cake, I used 3 ounces unsweetened chocolate and it was perfectly dark. I want to get the same results. Help!
