Start by placing the chilled water and passion fruit juice in a blender. Blend until the mixture is smooth.
Then, using the blender running, gradually add the powdered milk, beating well after each addition, until the mixture is smooth and creamy.
Then pour the mixture into a container of your choice or directly onto the worktop, whichever you prefer, and place in the freezer for approximately 2 hours.
Finally, after the freezing time, remove the dessert from the freezer and serve to enjoy this refreshing treat!
