Place all the ingredients in a blender and blend until the sugar has dissolved and the mixture is smooth and creamy. Place in a large bowl, cover, and chill in the fridge for at least one hour.
Prep an ice cream maker, add the orange sherbet mixture, and allow to churn as per the ice cream maker's instructions, usually around 40 minutes. Store finished sherbet covered in the freezer for up to two weeks.
Make this "no churn" buy pouring into a freezer-safe container, cover, and freeze for 6 hours, or overnight.
