Does anyone know the best way to color modeling chocolate? Can I color small amounts with gel food coloring after it's made? Or should I add color as I am making it?

Yes. I usually make a whole batch of white and color whatever and whenever I need. I just keep it in a zip-lock bag in my cupboard.

If I want to color a batch while I'm making it (dark colors or black) I use powdered color. Once the batch has been made, I can break off a little and add the color in.

Thanks!!

do any of you have a good recipe for modelling chocolate? i need to make a wedding that, instead of rolled fondant, it needs to be chocolate fondant.

is chocolate fondant, chocolate paste and modelling chocolate all the same? Can i cover a cake with all 3

No they are all different, fondant and modeling chocolate are 2 different things, modeling chocolate is just corn syrup and melted chocolate.., fodant is totally different. google search them and you will get more info.

Which one can be used to cover cakes?
