Beat the egg whites with the salt until stiff, add half of the sugar and continue to beat until the mixture turns glossy. Add the remaining sugar, lemon zest and juice, continue to beat until the mixture becomes very stiff. Divide the mixture into 8 portions, spread in circles on a baking tray lined with baking paper (each approx. 10 cm in diameter), pull the edges up slightly with a spatula.
Bake for approx. 10 mins. in the lower half of an oven preheated to 150°C. Turn the oven down to 120 °C and allow the pavlovas to dry for approx. 50 mins. Then switch the oven off and leave the pavlovas to cool in the oven with the door open.
Spread the passion fruit on top of the pavlovas, top with the mango, chocolate and mint.
