Whip the eggwhites in a grease free bowl until soft peaks. Slowly add the sugar until the meringue is glossy.
Put the cornstarch through a sieve and fold it into the eggwhites together with the vinegar
On a baking tray lined with baking paper make a circle of about 18 cm wide of the meringue and put it in the oven. Turn down the oven temperature to 120 C and leave it in for an hour. Turn the oven off and let the pavlova cool in the oven completely.
Once cooled you can top the pavlova with whipped cream and as I did with pomegranate and cranberry sauce.
Note
I wanted to keep the topping of this recipe in red but you can ofcourse add whatever you like on top of the pavlova. Raspberries, blueberries, passionfruit or mmm, warm cherries!
