Whip the cream and confectioners' sugar to soft peaks.
Start assembling the Pavlova by setting the meringue nest on a cake stand. Pile the whipped cream in the well of the nest. Next, pile on scoops of the mango and passion fruit sorbets. Arrange mango pieces around the edge of the sorbet. Drizzle the passion fruit over the top. Finally, scatter over the pistachios and mint leaves.
