Sour Cream-Lemon Pie

Directions

1. 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°.
2. Line 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 golden brown, 20-25 minutes. Remove foil and weights; bake until bottom is golden brown, 3-6 minutes longer. Cool on a wire rack.
3. In a large heavy saucepan, mix sugar and cornstarch. Whisk in milk and lemon juice until smooth. Cook and stir over medium-high heat until thickened and bubbly. Reduce heat to low; cook and stir 2 minutes longer. Remove from heat.
4. In a small bowl, whisk a small amount of hot mixture into egg yolks; return all to the pan, whisking constantly. Bring to a gentle boil; cook and stir 2 minutes. Remove from heat. Stir in butter and lemon zest. Cool without stirring.
5. Stir in sour cream. Add filling to crust. Top with whipped cream. Store in the refrigerator.
