1 (9 inch) graham cracker crust, plus 1/4 cup extra crumbs
3 eggs, separated
1 can sweetened condensed milk
Juice and grated rind of 1 1/2 lemons
Pinch of salt

Beat egg yolks well. Stir in milk, lemon juice, salt and rind. Whip egg whites until stiff. Fold in lemon mixture and pour into crust. Sprinkle with crumbs.

Bake 40 minutes at 325 degrees. Chill before serving. You can double this and bake in a 9 x 13 inch pan and serve in squares.
