← Hi Truffle Guy, I can give you my two cents on this. My wife and I employ this technique in decorating some of our molded chocolates. It uses a lot of cocoa butter compared to airbrushing or painting, and is not the cleanest of techniques. Though mess can be minimized by placing molds in rows, right up against each other, or covering your table with plastic wrap. First you need to find yourself a nice flexible small whisk. Second you melt your cocoa butter color (PCB, or Chef Rubber) in a container that is large enough to dip your whisk into. Make sure it doesn't get too hot or it will stick to the molds. Then pretend that you are Jackson Pollock and fling the cocoa butter into the molds by "whipping" the whisk. It is a little hard to explain, but it is like trying to get all the water off of a whisk. Just whip it and it will throw off lines of cocoa butter. You can also "splatter" the molds by tapping most of the cocoa butter back into the container and then utilize the same motion. This will give you more spots than lines. Of course for either one, all the molds will be different. Some will have the perfect lines you are looking for, and some will not be exactly what you are looking for. Christopher Elbow and Norman Love just picked the chocolate that they felt turned out best and had that one photographed. Hope that helps!
