This lemon meringue pie, inspired by the version Ann Landers famously shared in her column, is a classic American dessert with a bright, tangy lemon curd and a cloud-like toasted meringue topping. It works because the filling is cooked on the stovetop until thick and glossy, ensuring it sets properly without weeping, while the meringue is stabilized with a hot syrup for a marshmallow-soft finish that holds its shape. Serve it chilled for a refreshing end to any meal.
Ingredients
- 1 9-inch baked pie crust (store-bought or homemade), cooled
- 1 cup (200 g) granulated sugar
- 1/4 cup (30 g) cornstarch
- 1/4 teaspoon salt
- 1 1/2 cups (355 ml) water
- 4 large egg yolks, lightly beaten
- 1/2 cup (120 ml) fresh lemon juice (about 3 lemons)
- 1 tablespoon lemon zest (about 1 lemon)
- 2 tablespoons (28 g) unsalted butter, cut into pieces
- 4 large egg whites, at room temperature
- 1/2 teaspoon cream of tartar
- 1/2 cup (100 g) granulated sugar (for meringue)
- 1/4 cup (60 ml) water (for meringue)
- 1/2 teaspoon vanilla extract
Instructions
- Prepare the pie crust: If using a homemade crust, bake it blind (with pie weights) at 375°F (190°C) for 15 minutes, then remove weights and bake 5–7 minutes more until golden. Cool completely on a wire rack.
- Make the lemon filling: In a medium saucepan, whisk together 1 cup sugar, cornstarch, and salt. Gradually whisk in 1 1/2 cups water until smooth. Place over medium heat and cook, stirring constantly, until the mixture thickens and comes to a gentle boil, about 5–7 minutes. Boil for 1 minute, then remove from heat.
- Temper the egg yolks: Slowly whisk about 1 cup of the hot sugar mixture into the beaten egg yolks, a little at a time, to warm them without scrambling. Pour the yolk mixture back into the saucepan, whisking constantly.
- Return the pan to medium heat and cook, stirring constantly, until the filling is thick and bubbling, about 2–3 minutes. Remove from heat and stir in the lemon juice, lemon zest, and butter until the butter is melted and the filling is smooth.
- Pour the hot filling into the cooled pie crust. Cover the surface directly with plastic wrap to prevent a skin from forming. Let cool to room temperature, about 30 minutes, then refrigerate while you make the meringue.
- Make the meringue: In a small saucepan, combine 1/2 cup sugar and 1/4 cup water. Bring to a boil over medium-high heat, without stirring, until the syrup reaches 240°F (115°C) on a candy thermometer, about 5–7 minutes.
- While the syrup heats, place the egg whites and cream of tartar in a large, clean mixing bowl. Beat with an electric mixer on medium speed until soft peaks form, about 2–3 minutes.
- With the mixer running on low, slowly pour the hot syrup in a thin stream down the side of the bowl. Increase speed to high and beat until the meringue is glossy and stiff peaks form, about 5–7 minutes. Beat in the vanilla.
- Assemble: Remove the plastic wrap from the cooled pie. Spoon the meringue over the filling, spreading it to the edges to seal. Use the back of a spoon to create decorative peaks.
- Brown the meringue: Use a kitchen torch to toast the meringue, or place the pie under a preheated broiler for 1–2 minutes, watching closely, until lightly browned. (If broiling, keep the pie at least 4 inches from the heat.)
- Chill the pie in the refrigerator for at least 2 hours before slicing to allow the filling to set completely.
Tips
- Use fresh lemon juice: Bottled juice lacks the bright, clean flavor of fresh lemons. For the best taste, squeeze your own.
- Seal the meringue to the crust: Spread the meringue all the way to the edges of the pie crust to prevent shrinking and weeping.
- Don’t over-boil the filling: Once it bubbles, cook only for 1–2 minutes. Overcooking can make the cornstarch break down and the filling thin.
- If you don’t have a candy thermometer, test the syrup by dropping a little into cold water; it should form a firm ball that holds its shape.
Serving Suggestions
Serve chilled, straight from the refrigerator. For a pretty presentation, garnish each slice with a thin lemon twist or a few fresh berries. This pie pairs wonderfully with a cup of black coffee or a crisp herbal tea.
Variations
- Lime Meringue Pie: Replace the lemon juice and zest with equal amounts of fresh lime juice and zest for a tropical twist.
- Graham Cracker Crust: Swap the pastry crust for a graham cracker crust (about 1 1/2 cups crumbs mixed with 6 tablespoons melted butter) for a sweeter, crunchier base.
- Add a splash of coconut: Fold 1/2 cup toasted shredded coconut into the meringue before spreading for extra texture and flavor.
Storage and Reheating
Store leftover pie in the refrigerator, loosely covered, for up to 3 days. The meringue may soften over time, but it will still taste delicious. Do not freeze the assembled pie, as the meringue will weep and the filling may separate. If you have leftover filling (unlikely!), you can refrigerate it separately for up to 3 days and use it as a pudding.
Frequently Asked Questions
Why does my meringue weep? Weeping occurs when the meringue is undercooked or the filling is too hot when you spread it. Make sure your filling is completely cool (room temperature) before topping, and cook the meringue to at least 160°F (71°C) to stabilize it.
Can I use a store-bought crust? Absolutely. A refrigerated or frozen pie crust works well. Just be sure to bake it according to package directions and cool it completely before filling.
Can I make this pie ahead of time? Yes, you can make it up to 1 day in advance. Keep it refrigerated and add the meringue just before serving for the best texture.
What if I don’t have a candy thermometer? You can use the cold-water test: drop a small amount of syrup into a bowl of cold water. If it forms a firm, pliable ball, it’s ready. This stage is about 240°F (115°C).
Can I use frozen lemon juice? Yes, but make sure it’s 100% lemon juice with no added sugar. Thaw it completely before using.
Why is my filling runny? The filling may not have been cooked long enough. The cornstarch needs to reach a full boil to thicken properly. Also, be sure to measure the cornstarch accurately—too little will result in a loose filling.
