Whisk egg yolk and sugar on a hot water bath for approx. 10 minutes until creamy. Let the cream cool down a little. Peel the mango, cut the flesh off the stone. Put 8 thin slices aside and puree the rest of the fruit flesh. Whip cream until stiff. Stir crème fraiche and cream into the cream.
Rinse a small box mould (3/4 litre capacity) with cold water. Fold half of the mango puree into the cream and fill into the tin. Leave the mango parfait to set overnight in the freezer. Dip parfait briefly in hot water, turn it over on a board and cut it into 8 slices. Arrange mango parfait with the rest of the mango puree and mango slices on plates. Decorate with the exotic fruits and mint
Waiting time approx. 12 hours
