Follow these detailed steps to make your Autumn Pavlova with Apples, Maple Cream, and Salted Caramel:

1. Preheat Oven: Preheat your oven to 225°F (110°C). Line a baking sheet with parchment paper.
2. Prepare Meringue: In a clean, dry bowl, beat the egg whites on medium speed until soft peaks form.
3. Add Sugar: Gradually add the granulated sugar, one tablespoon at a time, while continuing to beat. Increase the speed to high and beat until stiff peaks form and the mixture is glossy.
4. Incorporate Vinegar and Cornstarch: Gently fold in the white vinegar and cornstarch using a spatula until combined.
5. Shape Meringue: Spoon the meringue onto the prepared baking sheet, creating a circle about 8-10 inches in diameter. Use the back of a spoon to create a slight well in the center for the toppings.
6. Bake: Place the meringue in the preheated oven and bake for 1 hour. Turn off the oven and leave the meringue inside to cool completely, preferably for at least 1 hour.
7. Prepare Maple Cream: In a mixing bowl, beat the heavy cream until soft peaks form. Gradually add maple syrup and continue to beat until stiff peaks form.
8. Prepare Apples: While the meringue cools, prepare the apples. Toss the thinly sliced apples with a sprinkle of cinnamon for added flavor.
9. Assemble Pavlova: Once the meringue has cooled, carefully transfer it to a serving platter. Spoon the maple cream into the center of the meringue.
10. Add Apples: Arrange the sliced apples on top of the maple cream.
11. Drizzle with Caramel: Generously drizzle the salted caramel sauce over the apples and cream.
12. Serve Immediately: If desired, dust with a little extra cinnamon before serving.
