Ingredients

  • 1 (9 inch) pie crust, baked
  • 5 tablespoons cornstarch
  • 1 cup white sugar
  • 1/4 teaspoon salt
  • 2 cups water
  • 3 egg yolks
  • 2 tablespoons butter
  • 5 tablespoons lemon juice
  • 2 teaspoons lemon zest
  • 3 egg whites
  • 6 tablespoons white sugar

Method

  • Preheat oven to 350 degrees F (175 degrees C).
  • To Make Lemon Filling: In a double boiler, combine cornstarch, sugar, and salt. Stir in water, mixing well. Cook until mixture is thickened, stirring frequently. Remove from heat.
  • Place egg yolks in a medium bowl and beat well. Slowly pour 1/2 cup of cornstarch mixture into egg yolks, whisking constantly.
  • Pour egg yolk mixture back into cornstarch mixture in double boiler, continuing to whisk constantly. Return double boiler to heat and cook mixture 2 minutes longer, stirring constantly. Remove from heat.
  • Stir butter or margarine, lemon juice, and lemon rind into thickened mixture. Allow mixture to cool, then pour into pie shell.
  • To Make Meringue: In a large metal or glass mixing bowl, beat egg whites until foamy. Add 6 tablespoons sugar a little at a time, continuing to beat until all sugar is incorporated and whites are stiff. Spread meringue into pie shell, making sure to completely cover lemon filling.
  • Bake in preheated oven for 15 minutes, just until meringue is golden brown. Chill before serving.
