Add about two-thirds of the chocolate to a heatproof bowl set over a pot of gently simmering water. Let chocolate melt until it reaches 40°C/100°F on a food thermometer.
To temper the chocolate, remove the bowl of melted chocolate from the heat, and add the remaining one-third chocolate, stirring constantly, until you reach a temperature of 32°C / 89°F. Use as needed, allowing the finished product to set in the fridge for approx. 12 hrs. Enjoy!
