Preparation:
In a sauce pan bring sugar and water to a boil. Reduce the heat to simmer and stir until sugar has completely dissolved and water appears clear. Cool completely.
Place the cooled sugar water into an ice cream maker, add the Star Apple and process until the mixture freezes. Place in fridge till set.
If you do not have an ice cream maker, mix all ingredients and put them into a plastic container. Freeze until partially set then beat thoroughly and freeze over night.
