Tangy Lemon Delight: The Ultimate Pie Recipe!

Preheat the 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 the double boiler, continuing to constantly whisk. Return the double boiler to heat and cook mixture 2 minutes longer, stirring constantly. Remove from heat.

Stir butter or margarine, lemon juice, and lemon zest 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.
