Put the coconut and the sugar together in a bowl and stir together.
Put the egg white in another bowl and whisk this loosely for a second or so.
Dip each glass into the egg white first and after that into the coconut-sugar mixture. Leave to dry.
Make the mousse by cleaning the mango and putting the flesh into a blender. Add the dragon or passionfruit and the juice of the lemon. Puree everything and then put it through a sieve to remove all the seeds.
Soak your gelatine leaves in cold water for about 5 minutes. Heat the cream on the stove until almost boiling, add the gelatine to it and stir until dissolved. Add this to the mango mixture.
Mix the eggwhites till firm, add the sugar and mix until glossy and stiff peaks form. Fold this carefully through the mango mix
Pour into the glasses and leave to set in the fridge
Decorate with some pomegranate and the grated coconut or use coconut cream.
Notes
According to the original recipe I had to use two leaves of gelatine which I did, but considering the fact it didn't really set very well I would use three leaves for next time
