Strain the seeds from the pulp and reserve. If you feel you have no pulp left, you may need to add more passionfruit to the recipe at this stage. It will depend on the variety of passionfruit used.
Freeze the pulp into ice cube trays until completely solid.
Place sugar and lemon zest into TM bowl and mill 10 sec/speed 10.
Add passionfruit pulp and egg white and mix 30 sec/speed 9.
Add reserved seeds to the mixture if desired. (Perhaps not all of them!)
Whip 20 sec/Butterfly/speed 4.
Serve immediately or place into a container and freeze.
This keeps its lovely spoon-able texture when served straight from the freezer.
