Cooking in My Kitchen: Lemon Custard Pie

Cooking in My Kitchen. This Lemon pie recipe is one my Mother and I made many times. You really have to add the ingredients in the order listed.
Trust me I did it once out of order and it really did not come out good.

This time around I think my egg whites could have been fluffier, non the less it was still pretty good.
Recipe
1 Lemon, grated rind and juice
2/3 cup of sugar
1 1/3 Tablespoons of flour (1/3 tablespoon is a teaspoon)
2 egg yolks, beaten
2/3 cup of milk
2 teauspoons butter, melted
2 egg whites, beaten
Mix the ingredients in the order given, folding in the egg whites last. Pour mixture into an unbaked shell.
Set plate low down in a hot oven 425° for 20 minutes or until the pastry is cooked on the bottom.
Remove to the center shelf of the oven, reducing tempreture heat to 325° for another 25 minutes or bake until mixture will not adhere to the point of a knife inserted in the center.
