AG: I begin with sketches. Then I create a scale drawing that is proportional to the dimensions of what I will sculpt. I make the structural pieces, which have to set overnight before I can assemble them. Then I use chocolatier tools, wood-carving tools, and clay-sculpting tools for shaping and adding fine details. To add color, I airbrush the surface with cocoa butter tinted with edible pigments. To finish, I polish the sculptures with a clean, slightly wet sponge.
