Ingredients
5 large egg whites, room temperature
Cream of tartar
3/4 cup granulated sugar
3/4 cup granulated sugar
8 large egg yolks
2 tablespoons orange zest, plus 1/2 cup orange juice (from 2 oranges)
1/4 cup lemon juice (from 2 lemons)
Fine salt
1 1/4 cups cold heavy cream
1 tablespoon confectioners’ sugar
1/2 ounce white chocolate, shaved with a vegetable peeler
Preparation
Preheat oven to 200 degrees. Make meringue: Trace a 10-inch circle onto a piece of parchment paper. Turn over and use parchment to line a baking sheet. In a large bowl, using an electric mixer, beat egg whites and pinch of cream of tartar on high until soft peaks form, about 2 minutes. With mixer running, add granulated sugar in a slow, steady stream and continue to beat on high until whites are very stiff and glossy and sugar is dissolved, 5 minutes.
With an offset spatula, gently shape meringue into a round on parchment-lined sheet, using circle as a guide; smooth top (make center slightly concave). Bake meringue until outside is dry, 2 hours. Turn off oven and let meringue cool completely in oven, about 5 hours (or up to overnight).
Make curd: In a medium saucepan, off heat, whisk together granulated sugar, egg yolks, and orange zest; whisk in orange and lemon juices and pinch of salt. Place pan over medium-high and cook, whisking constantly, until mixture is thick enough to coat the back of a spoon and small bubbles form around edge of pan, 5 minutes (do not let boil). Immediately remove pan from heat while whisking. Pour through a fine-mesh sieve into a heatproof bowl, pressing on curd with a rubber spatula. Press plastic wrap against surface; refrigerate until cool, 30 minutes (or up to 2 weeks).
Make topping: In a large bowl, using mixer, beat cream and confectioners’ sugar on high until stiff peaks form, 3 minutes. Gently peel meringue from parchment and transfer to a platter. Spoon curd in center and top with whipped cream and white chocolate shavings. Serve immediately.
