AI am make a few cupcakes for a friends beach themed wedding. She wants white chocolate shells on the cupcakes, I was thinking it might ba a little more realistic to add a little color but I'm not sure hoe to make the color dust stick. On fondant I know steaming sets the color but chocolate would just melt right? TIA

mix oil-based food coloring with melted chocolate to get desired color(s), then paint/dab/rub your colored chocolate inside your mold in spots/lines/streaks, then fill your mold like normal with uncolored chocolate. let pieces firm up completely, then pop out of mold.
