Preheat Oven: Preheat your oven to 300°F (150°C) and line a baking sheet with parchment paper.
Prepare Ingredients: Separate 4 large egg whites, ensuring no trace of yolks.
Whip Egg Whites: Using a clean, dry bowl and beaters, whip the egg whites on high speed until stiff peaks form
Add Sugar: Gradually add 1 cup of granulated sugar, one tablespoon at a time, while continuing to beat until the mixture is glossy and holds stiff peaks
Add Vinegar and Cornstarch: Gently fold in 1 teaspoon of white vinegar and 1 teaspoon of cornstarch until just combined.
Shape Pavlova: Spoon the mixture onto the prepared baking sheet, shaping it into a circle or oval with a slight indentation in the center
Bake: Place the pavlova in the preheated oven and immediately reduce the temperature to 250°F (120°C). Bake for 1 hour and 15 minutes to 1 hour and 30 minutes, or until the pavlova is crisp on the outside and dry to the touch.
Cool: Turn off the oven and let the pavlova cool completely inside the oven with the door slightly ajar.
Decorate: Once cooled, top the pavlova with whipped cream and fresh fruit, such as strawberries, kiwi, or passionfruit.
Serve: Slice and serve this airy, sweet dessert to impress your guests with its delicate texture and delicious flavor!
