Time 3h5m

Number Of Ingredients 9

3/4 cup sifted Cup4Cup flour
3 tablespoons cornstarch
1 1/4 cups superfine sugar
14 large egg whites (1 3/4 cups), room temperature
1 tablespoon warm water
1/2 teaspoon salt
1 1/2 teaspoons cream of tartar
2 teaspoons pure vanilla extract
Fresh berries and lightly sweetened whipped cream, for serving

Steps:

Preheat oven to 350 degrees. With a fine sieve, sift together flour, cornstarch and 3/4 cup sugar four times into a small bowl. Set aside.
In the bowl of a standing mixer, whisk together egg whites and warm water on medium speed until foamy. Add salt, cream of tartar, and vanilla; beat until soft peaks form, about 3 minutes. Increase speed to medium-high and sprinkle in remaining 1/2 cup sugar, 1 tablespoon at a time. Beat until stiff but not dry.
In six additions, sift dry ingredients over meringue, folding in quickly but gently. Pour batter into an ungreased 10-inch tube pan with removable bottom. Run a knife through the batter to release air bubbles. Smooth top with an offset spatula. Bake until golden brown and springy to the touch, 40 to 45 minutes. Invert pan on its legs and let cool completely, about 1 1/2 hours. Carefully run a long offset spatula or knife around the inner and outer perimeter of the pan to loosen. Arrange cake on a plate bottom-side up. Use a serrated knife to slice cake. Serve with berries and whipped cream. Store cake at room temperature up to 2 days in an airtight container or wrapped in plastic.
