Lemonade Meringue Pie Recipe

Line a 9-in. pie plate with pastry; trim and flute edges. Line unpricked pastry with a double thickness of heavy-duty foil. Bake at 450 ° for 8 minutes. Remove foil; bake 5-7 minutes longer or until lightly browned. Cool on a wire rack. Place egg whites in a large bowl; let stand at room temperature for 30 minutes. Meanwhile, in a large saucepan, combine the milk, sour cream and pudding mix until smooth. Cook and stir over medium heat until thickened and bubbly. Reduce heat; cook and stir 2 minutes longer. Remove from the heat. Stir a small amount of hot mixture into egg yolks; return all to the pan, stirring constantly. Bring to a gentle boil; cook and stir for 2 minutes longer. Remove from the heat. Gently stir in lemonade concentrate; keep warm. Add lemon juice and cream of tartar to egg whites; beat on medium speed until soft peaks form. Gradually beat in sugar, 1 tablespoon at a time, on high until stiff glossy peaks form and sugar is dissolved. Pour warm filling into pastry shell. Spread meringue evenly over filling, sealing edges to crust. Bake at 350 ° for 15-20 minutes or until the meringue is golden brown. Cool on a wire rack for 1 hour. Refrigerate for at least 3 hours before serving. Store leftovers in the refrigerator.
