I have a bag of the isomalt crystals and there is no direction on how to use it. Could you please help? I would like to make coral for a wedding cake with sea shells.

I think MYOM on this site gives clear instructions on the cooking process for isomalt. The coral is just, coloring it, then place either an ice block, or mounted ice on your work surface (silicone or silpat works nice-inside a pan/excess dripping water from ice) pour the sugar over the ice and as the ice melts you will get your coral.
