Boil the orange juice with the gelatine which you have allowed to soak for a little while first. Put this mixture in the refrigerator to firm up until it reaches the desired degree of thickness. Start by beating the egg white and then add a little sugar to it. Pour the egg white onto the boiling milk and cream. Bring mixture to 85°C (do not allow to boil). Then add the chocolate and put in the refrigerator to firm up. Peel the orange and remove every trace of the outer pith, then cut all the segments out from between the membranes. Bake the pancake and garnish it as shown in the photo.
