Wash your star fruits to get rid of impurities on the skin and cut the fruit into chunks.
If you use a blender, place the fruit chunks with the water and sugar into the blender jar and blend smooth.
Strain through a fine sieve before pouring into glasses with ice cubes.
If you use a juicer, simply press the fruit chunks through the juicer and collect the juice on the other side. Mix with sugar (powdered sugar will work better), water and ice cubes in a glass.
Serve cold
Notes
The number of fruits used in the recipe may vary depending on the size of the fruit.
