Preheat the oven to 300℉ and line a baking sheet with parchment paper. Draw an 8-inch circle in the middle of the parchment paper. This is where we mound the meringue on.
Leave the eggs outside the fridge a couple of hours before
Wipe all the tools with white vinegar, and wipe dry. Use the clean whisk attachment to whisk the egg whites, cream of tartar, and salt on low-medium speed until foamy and soft peaks form.
5 Egg whites, ¼ teaspoon Salt, ¼ teaspoon Cream of tartar
Add the cold water and caster sugar one tablespoon at a time, and take your time with this step, as it should take about one minute or so. Increase the speed to medium-high and whisk it until stiff and silky peaks form. This should take about 3-4 minutes.
2 tablespoon Cold water, 1¼ cups Sugar
Lastly, add the white vinegar, vanilla extract, and cornstarch and whisk for a few seconds until mixed.
1½ tablespoon Cornstarch, 2 teaspoon Vanilla extract, 1 teaspoon White vinegar
Place all the meringue on the circle, and use a spatula to gather it from the side to bring it to the top. Use the width of your spatula to create wide grooves all around the mass of the meringue. Make an opening on top, like the top of the volcano.
Turn the oven off and leave the pavlova inside for another two hours. Bake it for an hour until it turns a soft, light taupe colour. Before serving, top it with whipped cream and desired chopped fruit. Garnish it with some caramel sauce.
1 cup whipped cream, 2-3 tablespoon Caramel sauce, 1¼ cups Berries, 1 tablespoon Confectioner sugar for dusting
