1/4 c. flour
1 c. sugar
3 tbsp. cornstarch
1 1/2 c. boiling water
1 tbsp. butter
3 eggs, separated
1/4 c. lemon juice
1 tsp. grated lemon rind
1/2 c. cold water
Pinch of salt
9" baked pie shell

Combine flour, sugar, cornstarch and salt; add cold water and stir until smooth. Add boiling water and cook over low heat until thick and clear, about 20 minutes. Beat egg yolks and add a little of hot mixture and return to first mixture stirring constantly. When thick, remove from heat, about 5 minutes. Stir in butter, lemon juice and rind. Cool and pour into pie shell. Top with meringue made by beating 3 egg whites; add 3 heaping tablespoons marshmallow fluff and beat until stiff enough to hold peaks. Pile on filling and brown about 15 minutes at 400 degrees.
