1-1/3 cups all-purpose flour 
1/2 teaspoon salt 
1/2 cup shortening 
1 to 3 tablespoons cold water
FILLING: 
1-1/4 cups sugar 
1/4 cup cornstarch 
3 tablespoons all-purpose flour 
1/4 teaspoon salt 
1-1/2 cups water 
3 large egg yolks, lightly beaten 
2 tablespoons butter 
1-1/2 teaspoons grated lemon zest 
1/3 cup lemon juice
MERINGUE: 
1/2 cup sugar, divided 
1 tablespoon cornstarch 
1/2 cup cold water 
4 large egg whites 
3/4 teaspoon vanilla extract
1.  In a small bowl, combine flour and salt; cut in shortening until crumbly. Gradually add 3 tablespoons cold water, tossing with a fork until dough forms
a ball. 
2.  Roll out pastry to fit a 9-in. pie plate. Transfer pastry to pie plate. Trim to 1/2 in. beyond edge of plate; flute edges. Bake at 425° for 12-15 minutes
or until lightly browned. 
3.  For filling, in a large saucepan, combine the sugar, cornstarch, flour and salt. Gradually stir in water until smooth. Cook and stir over medium-high
heat until thickened and bubbly. Reduce heat; cook and stir 2 minutes longer. 
4.  Remove from the heat. Stir a small amount of hot filling into egg yolks; return all to the pan, stirring constantly. Bring to a gentle boil; cook and
stir 2 minutes longer. Remove from the heat. Gently stir in butter and lemon zest. Gradually stir in lemon juice just until combined. Pour into the crust.
5.  For meringue, in a saucepan, combine 2 tablespoons sugar and cornstarch. Gradually stir in cold water. Cook and stir over medium heat until mixture
is clear. Transfer to a bowl; cool. 
6.  In a large bowl, beat egg whites and vanilla until soft peaks form. Gradually beat in the remaining sugar, 1 tablespoon at a time. Beat in cornstarch
mixture on high until stiff glossy peaks form and sugar is dissolved. Spread evenly over hot filling, sealing edges to crust. 
7.  Bake at 350° for 25 minutes or until the meringue is golden brown. Cool on a wire rack for 1 hour. Refrigerate for at least 3 hours before serving.
Refrigerate leftovers.
