I have been taught that if I want black fondant, that I must buy a pack of chocolate fondant, then add black to it. However I have to go to a specialty cake shop to buy chocolate fondant. Is it possible to successfully colour white fondant black? With buttercream I just add cocoa powder first, then the black colour. Can something similar be done with fondant?
use brown coloring first, then add black
You can make chocolate MMF very easily doing just what you do with the BC...adding cocoa powder. Trade out about a half cup of powdered sugar for a half cup of cocoa and you will have a good start for your black.
I make MMF and add black to the marshmellows after I melt them, I also use colored mm. that gives them a brownish base, and adding my black color will really darken it before you are kneading it and it will keep its consitiancy better when you do have to tweak it with a little more black. Be warned it still takes ALOT of black. at least a bottle in my expeirience.
