To make the Pavlova: preheat the oven to 250 degrees F. Line a baking sheet with parchment.
To the bowl of a stand-up mixer, with the whisk attachment, add the egg whites and vinegar; beat until frothy, about 2 minutes. With the mixer running, slowly incorporate the sugar; beat until stiff peaks form, about 5 additional minutes. Mix in the vanilla extract.
Take a 5 or 6-inch plate, flip it over onto the parchment, and use it trace 3 circles. Divide the meringue evenly amongst circles, smoothing them out until they’re about 1-inch thick. Transfer to the oven to bake for 1 hour until hard and crisp on the outside. Turn the oven off, prop open the oven door, and allow to cool completely on the baking sheet.
To make the whipped cream: add the heavy cream and powered sugar to a bowl. Using an electric mixer, beat the cream and sugar together until fluffy, soft peaks form.
Place the first meringue disk on a plate. Top with 1/4 cup of heavy cream (feel free to eyeball this measurement) and smooth it out until it reaches the edges. Top with strawberry slices. Repeat until you’ve made three layers. For the top, add more strawberries and garnish with chamomile leaves and baby strawberries.
When you’re ready to plate, smash the meringue a bit with a knife and divide amongst bowls. That’s your mess!
