Use the sugar to make a dry caramel, then deglaze it with the cream and hot glucose.
Let the temperature fall to 75-80°C (165-180°F), then gradually pour the mixture onto the chocolate and use a spatula to create an emulsion. Immediately mix using an immersion blender to make a perfect emulsion.
At 40°C (105°F), add the clarified butter and mix using an immersion blender again.
Leave to set in the refrigerator.
