Welcome to the Cake Decorators Q&A
Chocolate compounds for ganache?
Can I use chocolate compounds for dark and milk chocolate ganache?
What could possibly go wrong if I use them?
Compound chocolate is fine to use. Use any chocolate you enjoy eating, just keep an eye on the cocoa solids.
Dark chocolate 45% and over, milk chocolate up to 42% and white chocolate up to 26 - 29% if you;re lucky.
