Take the egg whites out of the refrigerator about 30 minutes before use. Preheat the oven (electric cooker: 100 °C/circulating air: 75 °C/gas: see manufacturer). Draw a circle (approx. 18 cm Ø) on a sheet of baking paper.
Turn over baking paper and place on a baking tray.
For the meringue, beat the egg whites and 1 pinch of salt with the whiskers of the mixer until stiff. Gradually add sugar. Add vinegar and continue beating until the sugar has dissolved and the mixture is shiny.
Stir in the starch.
Spread the egg whites loosely with a tablespoon on the baking paper within the circle. Use the back of the spoon to press a depression into the mixture (later for cream and topping). Bake in the hot oven with the oven door slightly open (trick: pinch a wooden spoon handle in it!) for approx. 1 1⁄2 hours.
Switch off the oven. Let the meringue cool down with the oven door completely open.
For the topping, wash the berries and dab dry well. Clean and halve the strawberries. Halve the passion fruit and scrape out the pulp with a teaspoon. Put the cream and vanilla sugar in a mixing bowl and beat until stiff.
Pour the cream loosely into the bowl. Crown Pavlova with fruit.
