Preparation

• Pie crust:
  Preheat oven to 375 degrees.
  Roll the dough into a round 1/8 inch thick on a floured surface, drape it over a rolling pin, and fit it into a 9-inch pie pan.
  Press the dough firmly into the pan and cut off any excess with the floured rolling pin. Freeze any leftover dough for future use.
  Line crust with foil or parchment paper and weight with beans or pie weights.
  Bake at 400 degrees until edge is light golden brown, about 20 minutes. Remove the beans and foil, and continue cooking until bottom is dry, about 5 minutes. Cool to room temperature.
  In 2-quart saucepan stir together 1 cup sugar and corn starch. Gradually stir in water until smooth. Stir in egg yolks. Whisking constantly, bring to boil over medium heat and boil 1 minute. Remove from heat. Stir in lemon rind, lemon juice, and butter.
  Turn into pastry shell. In an electric beater, whisk egg whites at high speed until foamy.
  Gradually beat in sugar and continue beating to form stiff peaks. Spread some meringue around edge of filling first, touching crust all around, then fill in center.
  Bake in 325 F oven about 10 minutes or until lightly browned. Cool.
