1. Preheat the Oven:
- Preheat your oven to 300°F (150°C). Line a baking sheet with parchment paper.
2. Prepare the Meringue:
- In a clean, dry bowl, beat the egg whites until stiff peaks form.
- Gradually add the sugar, one tablespoon at a time, while continuing to beat the egg whites. Ensure the sugar is fully dissolved.
- Gently fold in the vinegar, cornstarch, and vanilla extract.
3. Shape the Pavlova:
- Spoon the meringue mixture onto the prepared baking sheet, shaping it into a circle or oval with a slight indentation in the center.
4. Bake:
- Place the pavlova in the preheated oven and immediately reduce the temperature to 250°F (120°C).
- Bake for 1.5 to 2 hours or until the pavlova is crisp on the outside and marshmallow-soft on the inside. It should be lightly golden.
- Turn off the oven and let the pavlova cool completely inside the oven with the door ajar.
5. Top and Serve:
- Once the pavlova is cooled, carefully transfer it to a serving platter.
- Whip cream until stiff peaks form, and spread it over the pavlova.
- Top with fresh fruits of your choice.
- Slice and serve.
Enjoy your homemade pavlova! Remember that pavlova is best served soon after assembly to maintain its crisp exterior and fluffy interior.
