# How to Make It:
01 - In a large mixing bowl, whisk together flour, salt, and sugar. Cut in cold cubed butter until the mixture resembles coarse crumbs. Add ice water one tablespoon at a time, mixing gently until dough just comes together. Shape into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour.
02 - Roll chilled dough on a lightly floured surface to fit a 9-inch pie dish. Press dough into dish, trim edges, and prick bottom with a fork. Line with parchment paper and fill with pie weights or dried beans. Bake at 400°F for 15 minutes, remove weights, and bake 8 to 10 minutes more until golden. Allow to cool completely.
03 - In a saucepan, whisk together sugar, cornstarch, and salt. Gradually add water while whisking until smooth. Cook over medium heat, stirring constantly, until mixture thickens and begins to bubble, approximately 5 to 7 minutes. In a separate bowl, whisk egg yolks. Slowly pour small amounts of hot mixture into yolks to temper, then whisk yolk mixture back into saucepan. Cook 2 minutes more while stirring. Remove from heat and stir in lemon zest, lemon juice, and butter until smooth.
04 - Pour prepared lemon filling into cooled pie crust. Allow to cool to room temperature before proceeding to meringue preparation.
05 - Using a clean mixing bowl and electric mixer, beat egg whites with cream of tartar on high speed until soft peaks form. Gradually add sugar while beating until stiff, glossy peaks form. Beat in vanilla extract until combined.
06 - Spread meringue topping over warm filling, ensuring that meringue contacts the pie crust edges completely to prevent shrinking during baking.
07 - Bake at 350°F for 15 to 18 minutes, or until meringue is golden brown. Allow pie to cool to room temperature, then refrigerate for at least 2 hours before slicing to ensure clean cuts.
