There are several ways of creating the supporting framework. One uses a small amount of glycerol, but, as with water addition, the process must be carried out quickly before the chocolate thickens. A Nestlé patent replaces some of the crystalline sugar by finely ground amorphous sugar. Particles of this material take in moisture and then transform it to the crystalline form. As they do so they eject the water molecules again, which stick them to the neighboring particles, before also enabling them to crystalline too. Over a period of weeks this chain reaction produces the full framework
