Ingredients

  • 1 (15 oz) pkg refrigerated pie crusts, room temperature
  • 1 large egg, separated
  • 7 medium apples, peeled, cored and sliced
  • 1 Tbsp lemon juice
  • 3/4 cup granulated sugar
  • 1/3 cup all-purpose flour
  • 1 1/4 tsp ground cinnamon
  • 3 Tbsp cold unsalted butter, cut into small pieces
  • 1 Tbsp sour cream

Method

  • Lightly grease a 9-inch pie plate. Roll 1 pie crust on lightly floured surface into 11-inch circle. Transfer crust to prepared pie plate. Trim dough leaving 1/2-inch overhang; brush with egg white. Set aside.
  • Preheat oven to 450 degrees. Place apple slices in large bowl; sprinkle with lemon juice. Stir together sugar, flour and cinnamon in small bowl. Add to apples; toss to coat apples evenly. Spoon apple mixture into pie crust; place butter pieces on top of apple mixture.
  • Moisten edge of crust with water. Roll second crust into 11-inch circle. Place on top of filling. Trim, leaving about 1/2-inch overhang. Seal edge.
  • Cut slits into crust at 1/2-inch intervals around edge to form flaps. Press 1 flap in toward the pie center and next flap out toward pie plate rim. Continue around pie edge. Cut 4 slits in top of dough to allow steam to escape.
  • Beat egg yolk and sour cream in bowl until blended. Cover; chill until ready to use.
  • Bake pie for about 10 minutes; reduce oven temperature to 375 degrees. Bake 35 minutes. Brush pie with egg yolk mixture. Bake until crust is light golden, about 20-25 minutes.
