Bob Hope's Lemon Pie

1 cup plus 2 tablespoons granulated sugar
3 tablespoons cornstarch
1 cup boiling water
4 tablespoons lemon juice
2 tablespoons butter
4 egg yolks
Pinch of salt
Grated rind of 1 lemon
3 egg whites
2 tablespoons granulated sugar
1 baked pie shell

Combine cornstarch and sugar. Add water slowly, stirring constantly until thick and smooth. Add slightly beaten egg yolks, butter, lemon rind, juice and salt. Cook for 2 to 3 minutes. Pour into baked pie shell. Cover with meringue made with egg whites and sugar stiffly beaten. Bake at 325 degrees F for 15 minutes or until meringue is light brown. Cool to room temperature before refrigerating to keep meringue from weeping.
