Preparation:
Whip the cream until soft and then mix with room temperature condensed coconut cream, lime juice and zest and vanilla sugar. If using rum, add that too. Mix everything until smooth and then pour into a storage box or mold with a lid, which you can use to put the ice cream in the freezer. Leave in the freezer for at least four hours if overnight.
Bring the ice cream to room temperature 10-15 minutes before serving, and then scoop the ice cream balls into hot water with an ice cream scoop. You can add lime slices and grated lime peel to the ice cream.
