3. Add to the eggs and sugar and mix well but without making it frothy.
4. Place the mixture in a pan of hot water on top of the stove and stir occasionally with a wooden spatule until the mixture coats the back of the spatule.
5. Add the drained leaf or melted powdered gelatine and stir until completely dissolved.
6. Pass through a fine conical strainer into a clean bowl and stand it in a container of iced water, stirring continuously until the mixture is on the point of setting.
7. Fold in the lightly whipped cream.
8. Pour into 2 x 13 cm moulds and place in a refrigerator until set.
