1 (9 inch) baked pie shell
4 egg yolks
1 1/2 c. sugar
1/4 c. cornstarch
1/4 c. flour
1/8 tsp. salt
1 3/4 c. boiling water
Grated rind of 2 lemons
1/2 - 2/3 c. lemon juice
2 tbsp. butter

1/8 tsp. salt
1/2 tsp. vanilla

In heavy saucepan mix sugar, cornstarch, flour and salt. Stir in boiling water slowly.

In separate bowl, beat egg yolks slightly with a fork. Stir at least half of the hot mixture into egg yolks. Blend into remaining hot mixture. Add rind and lemon juice and butter. Bring to boil, stirring constantly until clear and thick. Cool slightly. Fill baked pie shell.

Beat egg whites until foamy. Add 1/8 teaspoon salt, vanilla and 1/2 cup sugar slowly as it is whipping. Whip until stiff. Do not overbeat. Spread meringue on pie. Bake at 350 degrees for 10 minutes or until browned.
