Ingredients
Crust
- 1 ½ cups graham cracker crumbs
- 2 tablespoons granulated sugar
- 5 tablespoons unsalted butter, melted
Filling
- 2 teaspoons powdered unflavored gelatin
- ⅓ cup cold water
- 4 large eggs, separated (room temperature)
- ¾ cup granulated sugar (divided)
- ¼ teaspoon fine sea salt
- ⅓ cup fresh lemon juice
- 1 tablespoon lemon zest
Topping
- Whipped cream, for serving
Instructions
- Make the crust: Preheat the oven to 350°F. In a medium bowl, combine graham cracker crumbs, 2 tablespoons sugar, and melted butter, mixing until the crumbs are well moistened. Press the mixture evenly into the bottom and up the sides of a greased 9-inch pie plate using your hands or the bottom of a glass.
- Bake the crust: Place the pie plate in the preheated oven and bake for 10 minutes. Remove and let the crust cool completely before filling.
- Prepare the gelatin: Sprinkle the powdered gelatin over ⅓ cup cold water in a small bowl and set aside to bloom while you prepare the filling.
- Cook the lemon custard: In a double boiler, whisk together egg yolks, ½ cup sugar, sea salt, and lemon juice until well combined. Cook the mixture, stirring constantly, until thick enough to coat the back of a spoon.
- Combine gelatin and zest: Remove the custard from heat and whisk in the bloomed gelatin and lemon zest until fully incorporated. Chill the mixture in the refrigerator for 25-30 minutes, stirring occasionally, until it starts to thicken.
- Beat egg whites: In a medium bowl, beat the egg whites with an electric hand mixer until stiff peaks form. Gradually add the remaining ¼ cup sugar and continue beating until just combined.
- Fold egg whites into lemon mixture: Gently fold the egg whites into the lemon custard ¼ at a time using a rubber spatula, ensuring each addition is fully incorporated before adding more to maintain a light texture.
- Assemble the pie: Pour the filling into the cooled pie crust and smooth the top evenly.
- Chill to set: Refrigerate the pie for at least 3-4 hours until fully set and firm.
- Serve: Top slices with whipped cream and garnish with additional lemon zest curls if desired before serving.
Notes
- Ensure eggs are at room temperature to achieve better volume when beating the whites.
- Blooming gelatin properly is crucial to avoid lumps in the filling.
- If you don't have a double boiler, you can create one by placing a heatproof bowl over a pot of simmering water, making sure the bowl doesn't touch the water.
- This pie is best chilled overnight for optimal texture and flavor.
- Use fresh lemon juice and zest for the best bright, natural lemon flavor.
