2. In a saucepan, bring the cream and sugar to the boil, stirring constantly, then add the grapefruit juice.
3. Cut the chocolate into small pieces and add to the cream off the heat. Stir until the chocolate melts.
4. Add the grapefruit zest and sesame oil.
5. Pour the mixture into the verrines and chill for at least 2 hours.
