Key Lime Chiffon Pie Recipe

How to Make Key Lime Chiffon Pie

1. **Prepare the Lime Syrup:**
2. Combine 1 cup of water and 1 cup of granulated sugar in a small saucepan.
3. Bring to a simmer over medium heat, stirring until sugar dissolves.
4. Add the zest of 3 large limes (julienned), and simmer gently for 30 minutes.
5. Strain the syrup through a fine-mesh sieve; reserve 1/3 cup of the syrup and discard the rest.
6. **Prepare the Graham Cracker Crust:**
7. Preheat oven to 375°F (190°C).
8. In a food processor, combine 1 ½ cups graham cracker crumbs, ¼ cup packed brown sugar, the zest of 1 lime (grated), and 6 tablespoons (3 ounces) melted unsalted butter.
9. Process until the mixture is evenly moistened and holds together.
10. Press the mixture firmly into the bottom and up the sides of a 9-inch pie plate.
11. Bake for 8-10 minutes, or until lightly golden.
12. Let cool completely on a wire rack.
13. **Prepare the Key Lime Filling:**
14. In a small saucepan, gently heat the reserved 1/3 cup lime syrup.
15. Remove from heat and sprinkle 1 tablespoon of unflavored gelatin over the warm syrup; let soften for 1 minute.
16. Stir in 1 cup fresh key lime juice, ¼ cup granulated sugar, and 2 large egg yolks.
17. Cook over low heat, stirring constantly, until the mixture thickens and is slightly frothy (about 2-3 minutes). Do not boil.
18. Strain the mixture through a fine-mesh sieve into a bowl and let cool to room temperature.
19. In a clean bowl, beat 4 large egg whites with 4 tablespoons of granulated sugar using an electric mixer until stiff, glossy peaks form.
20. In another bowl, beat 1 cup heavy cream with 2 tablespoons of granulated sugar and 1 teaspoon vanilla extract until soft peaks form.
21. Gently fold the whipped cream into the egg whites, then gradually drizzle in the cooled lime mixture, folding until smooth and well combined.
22. Pour the filling into the cooled crust.
23. Refrigerate, uncovered, for at least 4 hours, or preferably overnight, until completely set.
24. **Optional Garnish:** Top with additional whipped cream and a lime wedge before serving.
