1 baked pie shell





Combine in the top of a double boiler:


1 cup sugar


5 to 6 tablespoons cornstarch


1/8 teaspoon salt.


Add very gradually:


2 cups milk.


Stir and cook these ingredients over, not in, hot water for about 8 to 12 minutes or until the mixture thickens. Cover and cook for about 10 minutes more, stir occasionally. Remove from heat. Pour a little of the mixture over 3 beaten egg yolks. Beat this and return the whole mixture to the double boiler. Cook and stir over boiling water for another 5 minutes. Remove from heat. Beat in 3 tablespoons butter


1/2 cup lemon juice


2 teaspoons grated lemon rind. Cool the custard, then pour into bakes pie shell. Cover with meringue





To make meringue:

Add: 1/4 teaspoon cream of tartar.

Top the lemon filling with the meringue and then bake for 10 to 15 minutes. That's it.
