AI just used a Swiss roll tin, sprayed it first with spray lite, then let it set

Lots of info here on cooking the isomalt but what if I needed to color the nibs?  I have several bags of the clear but need green to pour some beer bottles. Will my Americolor gel paste work?

You can melt it in the microwave and add the color. You'll have to stir it in, I use a metal spatula so that I can chip the cooled isomalt off and remelt it.

Thank you for the quick reply costumeczar:)
