Instructions

Step 1: Prepare the Crust

1. Preheat the oven to 350°F (175°C).
2. In a bowl, combine the graham cracker crumbs, sugar, and melted butter.
3. Mix until the crumbs resemble wet sand.
4. Firmly press the mixture into the bottom and up the sides of a 9-inch pie dish.
5. Bake for 8–10 minutes.
6. Remove from the oven and allow to cool.

Step 2: Make the Lemon Filling

1. In a medium saucepan, whisk together the sugar, cornstarch, and salt.
2. Gradually whisk in the water until smooth.
3. Cook over medium heat, stirring constantly, until the mixture thickens and begins to boil.
4. Reduce the heat to low.
5. Slowly whisk a few spoonfuls of the hot mixture into the beaten egg yolks to temper them.
6. Pour the tempered yolks back into the saucepan.
7. Cook for 2–3 minutes, stirring continuously.
8. Remove from the heat.
9. Stir in the lemon juice, lemon zest, and butter until smooth.
10. Pour the hot filling into the prepared crust.

Step 3: Make the Meringue

1. In a clean mixing bowl, beat the egg whites until foamy.
2. Add the cream of tartar.
3. Gradually add the sugar, one tablespoon at a time, beating continuously.
4. Beat until stiff, glossy peaks form.
5. Mix in the vanilla extract.

Step 4: Top the Pie

1. Spoon the meringue over the hot lemon filling.
2. Spread it all the way to the edges of the crust to seal the filling.
3. Create decorative peaks with the back of a spoon.

Step 5: Bake

1. Bake for 12–15 minutes, or until the meringue is lightly golden.
2. Remove from the oven.
3. Cool completely at room temperature.
4. Refrigerate for at least 4 hours before slicing.

Frequently Asked Questions (FAQs)

Q: Why did my meringue shrink?
A: The meringue may shrink if it isn’t spread all the way to the crust or if it is underbeaten.

Q: Why is my lemon filling runny?
A: It may not have been cooked long enough to activate the cornstarch, or the pie wasn’t chilled long enough before slicing.

Q: Can I use bottled lemon juice?
A: Fresh lemon juice is highly recommended for the best flavor, but bottled lemon juice can be used if needed.

Q: How do I know when the meringue is ready?
A: It should form stiff, glossy peaks that hold their shape when the beaters are lifted.

Q: Can I make the pie a day ahead?
A: Yes. Prepare it the day before and refrigerate until ready to serve.

Q: Can I toast the meringue with a kitchen torch instead of baking?
A: Yes. If the filling is already hot, you can brown the meringue evenly using a kitchen torch.

Q: Why does meringue sometimes weep?
A: Weeping can occur from overcooking, undercooking, or high humidity. Proper baking and cooling help reduce this.

Q: Can I make this gluten-free?
A: Yes. Simply use gluten-free graham crackers for the crust and ensure all other ingredients are certified gluten-free.
