Ingredients

  • 1-1/4 cups sugar
  • 6 tablespoons cornstarch
  • 2 cups water
  • 3 egg yolks
  • 3 tablespoons butter, cubed
  • 1/3 cup lemon juice
  • 2 teaspoons white vinegar
  • 1-1/2 teaspoons lemon extract
  • 1 pastry shell (9 inches), baked
  • 1/2 cup plus 2 tablespoons water
  • 1 tablespoon cornstarch
  • 3 egg whites
  • 1 teaspoon vanilla extract
  • Pinch salt
  • 6 tablespoons sugar

Method

  • In a large saucepan, combine sugar and cornstarch. Stir in water until smooth. Cook and stir over medium-high heat until thickened and bubbly. Reduce heat to low; cook and stir for 2 minutes longer. Remove from the heat. Stir 1 cup of hot filling into egg yolks; return all to pan stirring constantly.
  • Bring to a gentle boil; cook and stir for 2 minutes longer. Remove from the heat. Stir in butter. Gently stir in lemon juice, vinegar and extract. Pour hot filling into pastry shell.
  • For meringue, combine water and cornstarch in a saucepan until smooth. Cook and stir until thickened and clear, about 2 minutes.
  • Meanwhile, in a large bowl, beat the egg whites, vanilla and salt on medium speed until stiff peaks form. Gradually beat in sugar, 1 tablespoon at a time, on high until stiff glossy peaks form and sugar is dissolved. Gradually add cornstarch mixture, beating well on high. Immediately spread evenly over hot filling, sealing edges to crust
  • Bake at 350° for 12-15 minutes or until meringue is golden brown. Cool on a wire rack for 1 hour. Refrigerate for at least 3 hours before serving. Refrigerate leftovers.
