Ingredients:
- 1 1/4 cups (150g) all-purpose flour, plus more for dusting
- 1/2 teaspoon (2.5ml) salt
- 1/2 cup (113g) cold unsalted butter, cut into 1/2-inch cubes
- 1/4 cup (60ml) ice water
- 1 tablespoon (15ml) granulated sugar
- 1 1/2 cups (300ml) granulated sugar
- 1/4 cup (30g) cornstarch
- 1/4 teaspoon (1.25ml) salt
- 1 1/2 cups (360ml) water
- 1/2 cup (120ml) lemon juice, freshly squeezed (about 4-5 lemons)
- 4 large egg yolks
- 2 tablespoons (28g) unsalted butter, cut into cubes
- 1 tablespoon (15ml) lemon zest
- Yellow food coloring (optional, for a richer color)
- 4 large egg whites, at room temperature
- 1/4 teaspoon (1.25ml) cream of tartar
- 1/2 cup (100g) granulated sugar
- 1 teaspoon (5ml) vanilla extract
Instructions:
- Combine flour, salt, and sugar. Cut in cold butter using a pastry blender or your fingers until mixture resembles coarse crumbs.
- Gradually add ice water, mixing until dough just comes together.
- Form into a disc, wrap in plastic wrap, and chill for at least 1 hour.
- Roll out dough on a lightly floured surface and transfer to pie plate. Trim edges and crimp decoratively.
- Prick the bottom of the crust with a fork. Line with parchment paper and fill with baking weights or dried beans.
- Bake at 375°F (190°C) for 15 minutes. Remove weights and bake for another 5-10 minutes, or until lightly golden brown. Let cool completely.
- In a saucepan, whisk together sugar, cornstarch, and salt.
- Gradually whisk in water until smooth.
- Cook over medium heat, stirring constantly, until mixture thickens and comes to a boil.
- Reduce heat and cook for 1 minute, stirring constantly.
- In a separate bowl, whisk together egg yolks and lemon juice.
- Temper the egg mixture by slowly drizzling in a small amount of the hot sugar mixture, whisking constantly.
- Pour the tempered egg mixture back into the saucepan.
- Cook over low heat, stirring constantly, until filling thickens and coats the back of a spoon (or reaches 170°F/77°C on a thermometer).
- Remove from heat and stir in butter, lemon zest, and optional food coloring.
- Pour filling into cooled pie crust.
- In a clean, dry bowl, beat egg whites with cream of tartar until soft peaks form.
- Gradually add sugar, beating until stiff, glossy peaks form. Beat in vanilla extract.
- Immediately spread meringue over the lemon filling, making sure to seal it to the edges of the crust. Swirl the meringue for visual appeal.
- Bake at 350°F (175°C) for 12-15 minutes, or until meringue is golden brown.
- Let cool completely before slicing and serving.
