• Key Limes: Known for their intense, floral aroma and bright, acidic flavor with a hint of bitterness.
• Lemons: Have a more robust, pungent aroma and a sharper, sour taste with a lingering bitterness.

Can You Use Lemons in Key Lime Pie?

How to Make Key Lime Pie with Lemons

Ingredients:

• 1 graham cracker crust (pre-made or homemade)
• 1 cup granulated sugar
• 1/3 cup cornstarch
• 1/4 teaspoon salt
• 1 cup lemon juice (from about 6-8 lemons)
• 3 large egg yolks
• 1 tablespoon grated lemon zest
• 1/2 cup unsalted butter, softened
• 1 cup heavy cream, whipped

Instructions:

1. Prepare the crust: In a medium bowl, combine the graham cracker crumbs, sugar, and melted butter. Press the mixture firmly into the bottom of a 9-inch pie plate and refrigerate while preparing the filling.
2. Make the filling: In a medium saucepan, whisk together the sugar, cornstarch, and salt. Gradually whisk in the lemon juice until smooth. Bring to a boil over medium heat, stirring constantly. Reduce heat and simmer for 1 minute, or until thickened.
3. Temper the egg yolks: In a small bowl, whisk the egg yolks. Gradually whisk in about 1/2 cup of the hot lemon mixture into the egg yolks to temper them.
4. Combine the filling: Pour the tempered egg yolk mixture back into the saucepan with the remaining lemon mixture. Bring to a simmer over medium heat, stirring constantly. Cook for 2-3 minutes, or until the mixture has thickened and coats the back of a spoon.
5. Remove from heat: Stir in the lemon zest and butter until melted.
6. Cool the filling: Pour the filling into the prepared graham cracker crust and refrigerate for at least 4 hours, or overnight.
7. Top with whipped cream: Before serving, spread the whipped cream over the chilled pie.

Tips for Using Lemons in Key Lime Pie

• Use fresh lemons: Freshly squeezed lemon juice will provide the most intense flavor.

• Consider adding a hint of bitterness: A dash of Angostura bitters or a pinch of salt can add a subtle bitterness that complements the lemon flavor.
