Hi! I've been reading a lot of threads on eGullet and have learned a lot from everyone. Thanks a lot! Finally signed up for an account to be able to post. In Devil's Food cake, the reddish brown tint is supposed to be from the reaction of baking soda. And most DF cakes use soda and natural/unalkalized cocoa for the reaction. Now, my question is: is the color from the reaction of soda with the acidity of the natural cocoa specifically or would any acid reacting with soda in the presence of cocoa (natural or dutched) produce that color? More practically speaking, if dutched cocoa replaced natural in a DF cake, can the same reddish color be achieved by adding extra acid for the soda? I'd do a side-by-side comparison, but the whole question comes because natural cocoa is difficult to find where I live! So if anyone has experience or a theoretical answer, I'd really appreciate it!
