- Bring the cream and salt to steaming, do not boil it
- Add the cream to the chocolate in three inclusions making sure it is all incorporated every time more cream is added.
- Add the butter, in little bits.
- Mix until smooth and glossy ( if it splits, don’t worry, just blend it slightly with a hand blender or in a blender just be careful not to incorporate too much air.)
- Let set in the fridge for about 1 hour until thick before using
