Step-by-Step Instructions
Step 1: Prepare and Blind-Bake the Crust
-
Combine Dry Ingredients: In a large bowl, whisk together the flour, salt, and sugar.
-
Cut in the Butter: Add the cold, cubed butter. Work the butter into the flour mixture using a pastry cutter or your fingertips until the flour resembles coarse meal with pea-sized butter bits remaining.
-
Bind the Dough: Drizzle in ice water 1 tablespoon at a time, gently tossing with a fork until the dough begins to clump together. Form into a smooth disk, wrap in plastic, and chill in the refrigerator for 40 minutes.
-
Roll and Shape: Roll out the dough on a lightly floured surface to a 12-inch circle. Transfer it to your 9-inch pie dish, crimp the edges, and prick the bottom lightly with a fork. Chill in the freezer for 15 minutes.
-
Blind Bake: Preheat your oven to 375°F (190°C). Line the dough with parchment paper and fill with pie weights or dried beans.
-
Bake Time: 15 minutes at 375°F (190°C) (Medium-High Oven Intensity).
-
Uncover & Finish: Remove parchment and weights, then return to the oven for another 8 to 10 minutes until the bottom is pale golden and dry. Cool completely on a wire rack.
-
Step 2: Cook the Lemon Curd Filling
-
Mix Dry Ingredients: In a heavy-bottomed saucepan, whisk together 1 ½ cups sugar, cornstarch, and salt.
-
Add Liquid: Gradually whisk in 1 ½ cups water, ½ cup fresh lemon juice, and 1 tablespoon lemon zest until smooth and cornstarch is fully dissolved.
-
Thicken over Heat: Set saucepan over Medium Heat (Medium Intensity). Whisk continuously as the mixture heats up. As it approaches a boil, it will transform from cloudy to translucent and thicken rapidly. Allow it to come to a gentle boil for 1 full minute, whisking vigorously.
-
Temper the Yolks: In a medium bowl, lightly beat the 4 egg yolks. Slowly pour about 1 cup of the hot lemon mixture into the egg yolks while whisking constantly. This tempers the yolks so they do not scramble.
-
Combine and Finish: Pour the tempered yolk mixture back into the saucepan. Return to Medium-Low Heat (Low-Medium Intensity) and cook for another 2 minutes, whisking constantly until thick and bubbling.
-
Enrich: Remove from heat and stir in the 2 tablespoons of softened butter until fully melted and glossy. Strain through a fine-mesh sieve into a bowl if desired for maximum smoothness. Keep warm while making the meringue.
Step 3: Prepare the Swiss Meringue
Using a Swiss meringue method prevents weeping and ensures a stable structure.
-
Set up Water Bath: Fill a saucepan with 1 inch of water and bring to a simmer over Low Heat (Low Intensity).
-
Dissolve Sugar: In the clean glass or stainless steel bowl of your stand mixer, whisk together the 4 egg whites, ¾ cup sugar, and cream of tartar. Place the bowl over the simmering water (ensure the bottom does not touch the water).
-
Heat Mixture: Whisk constantly for 3 to 4 minutes until the sugar is completely dissolved and the mixture reaches 160°F (71°C) on a digital thermometer.
-
Whip to Stiff Peaks: Transfer the bowl to your stand mixer fitted with the whisk attachment. Add vanilla extract. Whip on High Speed (High Intensity) for 5 to 7 minutes until glossy, opaque white, and stiff peaks form.
Step 4: Assembly and Final Bake
-
Layer the Filling: Pour the hot lemon curd filling directly into the pre-baked pie shell. (Note: Adding meringue over warm filling helps seal the layers and prevents weeping.)
-
Top with Meringue: Dollop the meringue over the warm filling. Use an offset spatula to spread the meringue all the way to the edge of the crust, sealing the filling completely inside. Use the back of a spoon to pull up decorative swooshes and peaks.
-
Bake to Golden Perfection: Place the pie into the oven preheated to 350°F (175°C) for 10 to 12 minutes (Medium Intensity) until the meringue peaks are beautifully browned.
-
Chill and Set: Allow the pie to cool at room temperature on a wire rack for 2 hours, then refrigerate uncovered for at least 2 to 3 hours before slicing.
