Ingredients
Dough for single-crust pie2/3 cup sugar1/4 cup cornstarch1/4 teaspoon salt2 cups whole milk3 large egg yolks, lightly beaten1 cup sweetened shredded coconut, finely chopped2 tablespoons butter1/2 teaspoon vanilla extractMERINGUE:3 large egg white, room temperature1/4 teaspoon cream of tartar1/2 teaspoon vanilla extract6 tablespoons sugar1/2 cup sweetened shredded coconut
Preparation
On a lightly floured surface, roll dough to a 1/8-in.-thick circle; transfer to a 9-in. pie plate. Trim to 1/2 in. beyond rim of plate; flute edge. Refrigerate 30 minutes. Preheat oven to 425°.
Line unpricked crust with a double thickness of foil. Fill with pie weights, dried beans or uncooked rice. Bake on a lower oven rack until edge is light golden brown, 15-20 minutes. Remove foil and weights; bake until bottom is golden brown, 3-6 minutes longer. Cool on a wire rack. Reduce oven setting to 350°.
In a small heavy saucepan, mix sugar, cornstarch and salt. Whisk in milk. Cook and stir over medium heat until thickened and bubbly. Reduce heat to low; cook and stir 2 minutes longer. Remove from heat.
In a small bowl, whisk a small amount of hot mixture into egg yolks; return all to pan, whisking constantly. Bring to a gentle boil; cook and stir 2 minutes. Remove from heat. Gently stir in chopped coconut, butter and vanilla until butter is melted.
For meringue, in a small bowl, beat egg whites, cream of tartar, and vanilla on medium speed until foamy. Gradually add sugar, 1 tablespoon at a time, beating on high after each addition until sugar is dissolved. Continue beating until stiff glossy peaks form.
Transfer hot filling to crust. Spread meringue evenly over filling, sealing to edge of crust. Sprinkle with flaked coconut. Bake at 325° until meringue is golden, 15-18 minutes. Cool 1 hour on a wire rack. Refrigerate at least 3 hours before serving.
