would I be able to mix fondant and modeling chocolate?
I have a couple of questions, has anyone tried this and if so what was the consistency? is it the same as adding gumpaste or tylose?
How is the taste?
That's how I make my chocolate fondnt. It tastes awesome! Depending on how chocolately I want it to be, I add as much as a 50/50 mix. You can go less on the modeling chocolate and still get a great flavor and the same workability. The consistency is more dependant on the temperature. It can become soft easily from the warmth of the room or your hands from working it. It is less sticky than straight fondant, though. It does not act the same as adding tylose or gumpaste. Its kind of its own medium that takes some experience to learn how to work with.
I've done this in my zoo train cake to make it look like wood. Worked great. I wouldn't dare to cover a cake though. I would be scared of cracking on the folds.
