Preheat the Oven: Preheat your oven to 250°F (120°C) and line a baking tray with parchment paper.
Whip the Egg Whites: In a clean, dry bowl, beat the egg whites on medium speed until soft peaks form.
Add Sugar: Gradually add the granulated sugar, one tablespoon at a time, while continuing to beat. Continue until the mixture is glossy and forms stiff peaks.
Incorporate Cornstarch and Vinegar: Gently fold in the cornstarch and vinegar until just combined. This helps the meringue maintain its lovely texture!
Shape the Meringue: Spoon the meringue mixture onto the prepared baking tray, shaping it into a large circle or a nest shape with a slight dip in the center.
Bake: Place in the oven and bake for 1 hour, then turn off the oven and let it cool completely inside—a crucial step!
Prepare the Topping: Once cool, whip the heavy cream with powdered sugar and vanilla extract until soft peaks form.
Assemble: Carefully top the cooled pavlova with whipped cream and scatter your choice of fresh fruits on top.
Serve: Slice and serve immediately for the best texture. Enjoy the delightful contrasts of the crispy meringue and luscious cream!
