- Mix or blend fresh durian with fresh milk.
- Once that is smooth (or to your liking) add in caster sugar and continue to mix/blend until sugar is dissolved.
- Beat the heavy cream until stiff, and then transfer batch by batch into the durian mixture. Fold the whipped cream until it is well mixed.
- Transfer into a container; make sure it can be properly sealed to avoid crystallization on top of mixture once it is frozen. Leave it in the freezer for at least 5 hours.
