4 extra-large egg whites, at room temperature
Pinch of kosher salt
1 cup sugar
2 teaspoons cornstarch
1 teaspoon white wine vinegar
½ teaspoon pure vanilla extract
½ pint fresh strawberries, hulled and sliced
½ pint fresh blueberries ½ pint fresh raspberries
Sweetened Whipped Cream
1 cup cold heavy cream
1 tablespoon sugar
1 teaspoon pure vanilla extract
Triple Raspberry Sauce
1 half-pint fresh raspberries
½ cup sugar
1 cup seedless raspberry jam (12-ounce jar)
1 tablespoon framboise liqueur
Preheat the oven to 180 degrees. Place a sheet of parchment paper on a sheet pan. Draw a 9-inch circle on the paper, using a 9-inch plate as a guide, then turn the paper over so the circle is on the reverse side. (This way you won’t get a pencil mark on the meringue.)
Place the egg whites and salt in the bowl of an electric mixer fitted with a whisk attachment. Beat the egg whites on high speed until firm, about 1 minute. With the mixer still on high, slowly add the sugar and beat until it makes firm, shiny peaks, about 2 minutes. Remove the bowl from the mixer, sift the cornstarch onto the beaten egg whites, add the vinegar and vanilla, and fold in lightly with a rubber spatula. Pile the meringue into the middle of the circle on the parchment paper and smooth it within the circle, making a rough disk.
Bake for 1½ hours. Turn off the oven, keep the door closed, and allow the meringue to cool completely in the oven, about 1 hour. It will be crisp on the outside and soft inside. Invert the meringue disk onto a plate and spread the top completely with sweetened whipped cream.
Combine the strawberries, blueberries and raspberries in a bowl and toss with about ½ cup of raspberry sauce, or enough to coat the berries lightly. Spoon the berries carefully into the middle of the Pavlova, leaving a border of cream and meringue.
Serve immediately in large scoops with extra raspberry sauce.
Sweetened Whipped Cream Whip the cream in the bowl of an electric mixer fitted with a whisk attachment (you can also use a hand mixer). When it starts to thicken, add the sugar and vanilla and continue to beat until firm. Don’t overbeat!
Triple Raspberry Sauce Place the raspberries, sugar and ¼ cup water in a small saucepan. Bring to a boil, lower the heat, and simmer for 4 minutes. Pour the cooked raspberries, the jam, and framboise into the bowl of a food processor fitted with a steel blade and process until smooth. Chill.
