A very very thin skin of sugar crystals forms on the outside, with liquid left in the middle. You then dip these in chocolate, and decorate. Let me tell you, making three perfect dots of milk chocolate on the top of each one takes forever, especially when the chocolate keeps trying to cool down on you while you are working. A starch mold is sort of what it sounds like. You then make little dents in the starch, which you then fill with the candy.
More starch is sifted over the top.
By the way, this is how that Gummi Bears are made. Should be really neat looking come Friday.
