- 1 cup confectioners' sugar
 - 1/2 cup granulated sugar, plus
 - 1 tablespoon granulated sugar
 - 1 tablespoon cornstarch
 - 4 large egg whites, at room temperature
 - 1/2 teaspoon cream of tartar
 - 2 cups heavy cream
 - 1 teaspoon vanilla extract
 - 1 pint fresh raspberries
 - NOTE: You will need parchment paper for this recipe.
 
- The night before serving, adjust oven rack to lower-middle position and heat oven to 500 degrees.
 - Line a lipped cookie sheet (approximately 12 by 18 inches) with parchment paper. Trace two side-by-side rectangles – about 5 inches by 12 or 13 inches – on the paper. Crumple the paper, then smooth it out again and line the bottom of the pan.
 - Whisk together confectioner's sugar, 1/2 cup granulated sugar and cornstarch. Set aside.
 - In the bowl of a mixer, beat egg whites and cream of tartar until they turn from foamy to white and beaters just start to leave a trail. On low speed, add sugar mixture, a heaping tablespoon at a time. Increase speed to medium-high and beat to the consistency of marshmallow cream, 2 to 3 minutes longer.
 - Just before forming meringues, flick water onto parchment with fingertips. Divide meringue in half, spooning two or three mounds down each traced rectangle. Use a rubber spatula, or a cake decorator's metal offset spatula, to fill in and even out rectangles.
 - Set meringues in oven, close door and turn oven off (but leave oven light on). Let meringues dry overnight. Remove, then carefully set a wire rack or cookie sheet over meringues. Invert; peel off parchment and turn right side up. (It's OK if edges chip.) Wrap in foil and set aside until ready to proceed.
 - No more than two hours before serving, whip cream to soft peaks, beating in remaining sugar and the vanilla. Set one meringue on a platter. Spread with half the cream and sprinkle on half the berries. Repeat with remaining meringue, cream and berries. Refrigerate, uncovered, until ready to serve.
