Ingredients

• 5 large egg yolks, beaten: They provide richness and help thicken the filling. No substitute needed.
• 1 (14 ounce) can sweetened condensed milk: Adds sweetness and creaminess to the pie. Substitute not recommended for maintaining authenticity.
• ½ cup key lime juice: Gives the pie its signature tart and refreshing flavor. If unavailable, substitute with regular lime juice, though the taste will differ slightly.
• 1 (9-inch) prepared graham cracker crust: Provides a crunchy, sweet base for the pie. Use a store-bought crust for convenience or make your own if preferred.

How to Make It

Step 1: Prepare the Filling

In a large bowl, combine the beaten egg yolks and sweetened condensed milk. Mix until smooth. Slowly add the key lime juice, whisking continuously until the mixture is well blended and thick. The acidity of the lime juice naturally thickens the filling.

Step 2: Fill the Crust

Pour the prepared filling into the graham cracker crust, spreading it evenly with a spatula. It’s crucial to ensure that the filling is uniformly distributed to bake evenly.

Step 3: Bake the Pie

Preheat your oven to 350°F (175°C). Place the pie on a baking sheet for stability and bake for approximately 15 minutes, or until the filling sets slightly and the edges are just starting to firm. Avoid browning.

Step 4: Chill and Serve

Remove the pie from the oven and let it cool at room temperature for about 30 minutes. Then refrigerate for at least 2 hours to fully set. Serve chilled, optionally topped with whipped cream for extra indulgence.
