Demo
Starting with a clean dry textured mat, speedy Chef Derron spoons on red, tempered cocoa butter He then uses an offset spatula to spread the liquid cocoa butter thinly and evenly across the mat. Not too thick! The perfect thickness allows you to see the silicone detail through the red Cocoa Butter. Next, the entire mat is coated with a layer of dark tempered chocolate. As it sets, Chef Derron used cookie cutters to stamp out shapes Geometric shapes are incised using a metal Spatula. Don't use a Sharp Knife as you may inadvertantly damage the silicone mat. In just a few minutes, Chef Derron can create a variety of decorative elements. use these  beauties to embellish a dessert or showpiece. Or use them under a dessert for anew way to present your creations. Beautiful work! Thank you, Jean-Luc.
