Toast the coconut flakes in a large frying pan over a medium heat until golden brown. Remove from the pan and leave to cool. Thoroughly mix the coconut milk with the coconut blossom nectar and salt. Stir in 3/4 of the coconut flakes. Pour the mixture into a cake tin lined with cling film and freeze for at least 2 hrs.
Remove the ice cream from the freezer, allow to soften slightly, scoop out balls with an ice cream scoop and decorate with the passion fruit flesh, remaining coconut flakes and a little coconut blossom nectar.
