I lost sleep over this last night. While I could perfect the size of the pastry tip and the amount of chocolate on the tip when its pressed into the mold, the matte finish that @pastrygirl mentioned above is still bothering me.
So let's say that you dropped a chocolate ring into the mold. And, let's assume that you could form a ring, release it from whatever surface you formed it on, and you could move it into the mold without breaking it. Yes, that would get you the matte finish. But, that would cause problems when you go to spray because there would be a slight ridge that the spray would have to work around. I then zoomed in on my screen doing a 5x enlargement and you can then clearly see flaws in his ring.
My new conclusion - Make chocolate as normal, remove it from the mold, then take a large pastry tip or other ring, dip it in chocolate and press it onto the finished bonbon. That solves all of the problems and would give you a matte ring with no void or shadow from the spray, and would be doable (v. overly fragile).
I consider this mystery solved.
