• 2 tablespoons powdered sugar

Let’s Make Key Lime Pie!

Step 1: Crafting the Buttery Graham Cracker Crust

1. Preheat your oven to 350°F (175°C).
2. In your food processor, pulse graham crackers into fine crumbs. If you don’t have a food processor, place crackers in a zip-top bag and crush them with a rolling pin.
3. Combine graham cracker crumbs, sugar, and melted butter in a bowl. Stir until well combined and the crumbs are evenly moistened.
4. Press the mixture into the bottom and up the sides of your pie plate. Use the back of a spoon or your fingers to create an even crust.
5. Bake for 8-10 minutes, until lightly golden brown. Set aside to cool completely.

Step 2: Whipping Up the Zesty Key Lime Filling

1. In a large bowl, whisk together sweetened condensed milk and egg yolks until smooth.
2. Gradually whisk in the Key lime juice until fully incorporated. If using, stir in the lime zest.
3. Pour the filling into the cooled graham cracker crust.

Step 3: Baking to Creamy Perfection

1. Bake the pie for 15-18 minutes. The filling should be just set around the edges with a slight jiggle in the center.
2. Remove from the oven and let cool completely on a wire rack. Once cool, refrigerate for at least 3 hours (or preferably overnight) to allow the filling to fully set.

Step 4: The Finishing Touch – Whipped Cream and Zest

1. Just before serving, whip the heavy cream and powdered sugar in a chilled bowl until stiff peaks form.
2. Top the chilled pie with whipped cream. Garnish with lime slices and a sprinkle of lime zest, if desired.

Tips for Key Lime Pie Success

• Fresh Key lime juice is key! Bottled juice can sometimes have a slightly bitter aftertaste. If you can’t find fresh Key limes, look for bottled juice labeled “100% Key lime juice.”
• Don’t overbake the filling. Overbaking will result in a curdled, rubbery texture.
• For a smoother filling, strain it through a fine-mesh sieve before pouring it into the crust. This removes any bits of egg yolk and ensures a silky texture.
• Having trouble finding Key limes? Try a Key lime pie bar! These can be a delicious and convenient alternative. Check out our recipe for how to make Key lime cake for a fun twist on this classic flavor.
