Preheat oven to 250 degrees F.
With an electric mixer beat the egg whites until soft peaks form, then gradually add the sugar. Beat until firm. Add the cornflour, vinegar and vanilla. When combined, turn out onto a flat tray that has been greased and dusted with cornflour. Try a circular shape with slightly more mixture at the edges so that it forms a slight well for the whipped cream and fruit.

Cook in a pre-heated, cool (250 degrees F.) oven for one hour. When cooked, turn the oven off, leave the oven door slightly ajar, and allow to cool slowly in the oven. This slow cooling works to prevent the loss of too much height. Serve cold, with whipped cream and fruit, topped with the passion fruit pulp.
