Ingredients:
- 1 ¼ cups (150g) all-purpose flour, plus more for dusting
- ½ teaspoon salt
- ½ cup (113g) cold unsalted butter, cut into ½-inch cubes
- 3-5 tablespoons ice water
- 1 ½ cups (300g) granulated sugar
- ¼ cup (30g) cornstarch
- ⅛ teaspoon salt
- 1 ½ cups (355ml) water
- ½ cup (120ml) lemon juice, freshly squeezed (from about 3-4 lemons)
- 2 tablespoons (28g) unsalted butter
- 4 large egg yolks, lightly beaten
- 1 tablespoon lemon zest, finely grated
- ¼ teaspoon lemon extract (optional, for extra punch)
- 4 large egg whites, at room temperature
- ¼ teaspoon cream of tartar
- ½ cup (100g) granulated sugar
- ¼ teaspoon vanilla extract
Instructions:
- Combine flour and salt. Cut in cold butter until mixture resembles coarse crumbs.
- Gradually add ice water until dough just comes together.
- Form into a disc, wrap in plastic, and chill for at least 30 minutes.
- Roll out dough on a lightly floured surface.
- Transfer to pie plate, crimp edges, and prick bottom with a fork.
- Blind bake the crust: Line with parchment paper, add pie weights, and bake until lightly golden. Remove weights and parchment. Bake until fully golden and cooked through.
- In a saucepan, whisk together sugar, cornstarch, and salt.
- Gradually whisk in water until smooth.
- Cook over medium heat, stirring constantly, until thickened and bubbly.
- Remove from heat. Whisk a small amount of the hot mixture into the beaten egg yolks to temper them.
- Pour the egg yolk mixture back into the saucepan and cook, stirring constantly, until thickened.
- Remove from heat and stir in butter, lemon juice, lemon zest, and lemon extract (if using).
- In a clean, dry bowl, beat egg whites and cream of tartar until soft peaks form.
- Gradually add sugar, beating until stiff, glossy peaks form.
- Stir in vanilla extract.
- Pour the lemon filling into the pre-baked pie crust.
- Immediately spread the meringue evenly over the filling, ensuring it touches the crust all the way around to seal.
- Bake in a preheated oven until the meringue is golden brown. Alternatively, use a kitchen torch to brown the meringue.
- Cool completely before serving.
