Essential Ingredients for Key Lime Pie

4 large egg yolks
1 can (14 oz) sweetened condensed milk
½ cup freshly squeezed key lime juice

Step-by-Step Key Lime Pie Recipe
Step 1: Prepare the Crust
Preheat oven to 350°F (175°C)
Mix graham cracker crumbs, sugar, and melted butter in a bowl
Press the mixture firmly into a 9-inch pie pan
Bake for 8–10 minutes until lightly golden
Let the crust cool
Hack: Use the bottom of a measuring cup to compact the crust evenly.
Step 2: Make the Filling
Whisk egg yolks in a medium bowl until smooth
Add sweetened condensed milk and mix thoroughly
Stir in key lime juice and lime zest
Pour filling into cooled crust
Tip: Ensure the crust is completely cooled before adding filling to prevent cracking.
Step 3: Bake the Pie
Bake at 350°F (175°C) for 10–12 minutes until filling is set but slightly jiggly in the center
Do not overbake to maintain creamy texture
Hack: A water bath can help prevent cracks and create an ultra-smooth filling.
Step 4: Chill and Serve
Refrigerate for at least 2–3 hours before serving
Top with whipped cream and lime zest or slices
Tip: Chilling overnight improves flavor and texture.
