Get ready: Preheat your oven to 350 degrees. Line a baking (cookie) sheet with parchment paper, and set aside. Fit your electric mixer with the whisk attachment. Remove eggs from fridge, separate out the whites, and allow to warm to room temp (about 5 minutes).
In your mixer bowl, beat egg whites together with salt until glossy peaks form.
Slowly add in the sugar, and continue whipping until stiff peaks form. Turn off mixer, remove bowl.
Sprinkle cocoa, balsamic vinegar, cornstarch, and vanilla over meringue, gently fold in till combined.
Divide meringue into 2 rounds on your baking sheet.
Use a spatula to spread the meringue mounds into 2 rounds, about 7" in diameter. If you want to get really fancy, put the meringue into a pastry bag and pipe it out as a mass of swirls that form your 7″ circles! It’s really up to you! Put the baking sheet into your oven, and turn the temperature down to 250 degrees. Bake for 1 hour and 10 minutes.
Once your timer goes off, turn the oven off and let the meringues cool in the oven for several hours. The baking of the meringue can be done the day before, if needed!
Just before serving, whip the heavy cream.I like my pavlovas a little sweeter, so I add about 2 tablespoon of sugar – add as much or as little as you want. Purists may not want to sweeten the cream at all! I also like to add a little flavoring, again – optional Once heavy cream is whipped to the desired thickness, add the cocoa and vanilla, mix until well incorporated.
Place one pavlova meringue on your servings dish. Spread with half of your chocolate whipped cream, then top with half of your raspberries.
Carefully place the second meringue on top, spread with remaining whipped cream, arrange remaining raspberries on top.
Drizzle with Chocolate Sauce and serve immediately!
