A Brief History of Key Lime Pie
Key Lime Pie is a beloved dessert that originated in the Florida Keys. The pie is named after the small, tart Key limes that are grown in the region. Traditionally, the pie was made without baking, relying on the chemical reaction between the acidic lime juice and sweetened condensed milk to “cook” the filling. However, modern versions of the pie are often baked to ensure a firmer set. Key lime pie is recognized as the official state pie of Florida, and it remains a popular dish in the southern United States.
Key Ingredients and Why They Matter
Key Limes
Key limes are smaller and more acidic than regular limes, giving the pie its distinctive tart flavor.
- Substitution Tip: If you can’t find fresh Key limes, you can use bottled Key lime juice or a combination of regular lime juice and lemon juice for a similar flavor.
Sweetened Condensed Milk
The rich and creamy base of the pie comes from sweetened condensed milk, which sweetens and thickens the filling.
- Pro Tip: Make sure to use full-fat condensed milk for the best texture and flavor.
Graham Cracker Crust
A graham cracker crust provides the perfect crunchy contrast to the smooth filling. It’s lightly sweetened and buttery, complementing the tart lime flavor.
- Pro Tip: You can make the crust from scratch using graham crackers and butter, or use a store-bought crust for convenience.
How to Make the Best Key Lime Pie Ever
Step 1: Prepare the Crust
Ingredients:
- 1 1/2 cups graham cracker crumbs
- 1/4 cup granulated sugar
- 1/2 cup unsalted butter, melted
- Preheat your oven to 350°F (175°C).
- In a medium bowl, combine graham cracker crumbs, sugar, and melted butter. Stir until the mixture resembles wet sand.
- Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish.
- Bake the crust for 8-10 minutes, until it’s lightly golden. Remove from the oven and let cool while you prepare the filling.
Step 2: Make the Filling
Ingredients:
- 4 large egg yolks
- 1 can (14 oz) sweetened condensed milk
- 1/2 cup fresh Key lime juice (about 20-25 Key limes)
- 1 tablespoon Key lime zest (optional, for extra tang)
- In a medium bowl, whisk together the egg yolks until smooth. Add the sweetened condensed milk and whisk until fully combined.
- Gradually whisk in the Key lime juice and zest until the mixture is smooth and slightly thickened.
- Pro Tip: If you like your pie extra tart, add an additional tablespoon of Key lime juice.
Step 3: Bake the Pie
Pour the filling into the cooled graham cracker crust. Bake at 350°F for 15-17 minutes, or until the filling is just set but still slightly jiggly in the center.
- Pro Tip: Be careful not to overbake the pie. The filling will continue to set as it cools.
Step 4: Cool and Chill
Let the pie cool to room temperature, then refrigerate for at least 2 hours, or until fully chilled. This helps the flavors meld together and ensures the perfect texture for slicing.
Whipped Cream Topping
Ingredients:
- 1 cup heavy whipping cream
- 2 tablespoons powdered sugar
- 1 teaspoon vanilla extract
- In a large bowl, beat the heavy cream, powdered sugar, and vanilla extract with an electric mixer until soft peaks form.
- Spread or pipe the whipped cream over the chilled Key lime pie.
- Pro Tip: For a fun presentation, garnish the pie with lime zest or lime slices.
