Essential Ingredients

Fresh Key Limes: The star of the show! Look for vibrant limes with a smooth skin for maximum juiciness.
Graham Cracker Crumbs: For that perfect crust! You can buy them pre-made or crush some crackers yourself for a fresh touch.
Granulated Sugar: Sweetens up the tartness of the limes beautifully; it’s essential for balancing flavors.
Egg Yolks: These add richness and creaminess to your filling; make sure they’re at room temperature for best results.
Sour Cream: Enhances creaminess and adds a slight tang that complements lime perfectly; don’t skip this ingredient!
Butter: Unsalted is best! It binds the crust together and gives it a lovely flavor.
The full ingredients list, including measurements, is provided in the recipe card directly below.

How to Make Key Lime Pie
Prepare Your Crust: Preheat your oven to 350°F (175°C). In a mixing bowl, combine graham cracker crumbs, melted butter, and sugar until well-blended. Press this mixture firmly into a pie dish until evenly distributed.
Bake the Crust: Place your crust in the preheated oven and bake for about 10 minutes until golden brown. Let it cool completely before adding your filling; you want to avoid a soggy bottom!
Mix Your Filling: In another bowl, whisk egg yolks until they’re light and frothy. Gradually add in sweetened condensed milk and key lime juice while mixing continuously until everything is combined smoothly.
Add Sour Cream: Fold in sour cream gently into your mixture, ensuring it remains creamy without deflating too much. The consistency should be silky but not runny.
Bake Again: Pour your luscious filling into the cooled crust and smooth out the top with a spatula. Bake again at 350°F (175°C) for 15-20 minutes until set but still slightly wobbly in the center.
Chill Before Serving: Allow your pie to cool at room temperature before refrigerating it for at least three hours or overnight if you can wait that long! This step is crucial for flavor development.
Enjoy each slice of this Key Lime Pie as it tantalizes your palate with its zesty kick followed by creamy goodness. Serve chilled with whipped cream on top or even fresh lime slices if you’re feeling fancy!

FAQ
What type of limes should I use for Key Lime Pie?
Using fresh key limes is ideal for an authentic flavor profile, but if they’re hard to find, regular limes work too! Just keep in mind that key limes are typically smaller and have a more intense tartness compared to their larger counterparts.
Can I make Key Lime Pie ahead of time?
Absolutely! In fact, making it a day ahead enhances its flavor as it allows time for the filling to set properly. Just store it covered in the fridge until it’s time to serve.
How can I tell if my Key Lime Pie is done baking?
You’ll know your pie is ready when it’s set around the edges but slightly jiggly in the center; this means it’ll firm up as it cools. Overbaking can lead to cracks on top!
Is there a dairy-free alternative for Key Lime Pie?
Yes! You can make a delicious dairy-free version using coconut milk or cashew cream instead of heavy cream. These alternatives provide creaminess while keeping your pie rich and flavorful without dairy.
