Powdered Food Coloring
Right after modeling chocolate has just been handled, it’s soft from the heat of your hands, which makes it tacky so that powdered colors cling. You may use a small paint brush to add details or a blush brush to cover larger surface areas.
Use it to make a cake decoration look dirty, sandy, antique, weathered, skin-like, hide-like, shadowy or worn. In the above example, the modeling chocolate leaves were brushed with cocoa powder to enhance the detail of their veins. In the example below, modeling chocolate fairy flowers were dry brushed to give them shadow and sheen.
To keep a modeling-chocolate-covered cake dry while still holding it in the refrigerator, seal its surface under plastic wrap until it’s time to paint on the cake. Once you’ve painted the cake, don’t put plastic wrap on it again. Painted modeling chocolate is prone to smudging and should not be touched after the job is complete.
Using Powdered Food Color as a Paste: You can mix powdered colors or luster dusts with vodka or cocoa butter to make a wet paste. When modeling chocolate is too dry to accept powdered colors or when you want the color to go on thick, this method works well. It also allows for added detail and control.
Gel and Liquid Food Coloring
Painting onto modeling chocolate with gel or liquid food coloring is feasible but not ideal. The liquids tend to bead on the surface of modeling chocolate. You may have to paint over your design a few times in order to make it crisp. For this reason, liquid food coloring is not ideal for painting on modeling chocolate. Gel colors work better but may still be a challenge. In the whiskey bottle below, I hand painted the label using titanium dioxide (natural white food coloring). The color was too liquid for working on modeling chocolate so I thickened up its consistency with a little corn starch.
Airbrushing onto modeling chocolate may also result in the liquid beading on the surface, but it can still be done. Don’t airbrush heavily – going light is the key. Follow the tip above to achieve optimal results with an airbrush machine.
Edible markers are not the most compatible with modeling chocolate for the same reason that liquid colors are more difficult to apply. They also work best when the modeling chocolate is dry on the surface and dusted with cornstarch.
