How to Make Mom's Key Lime Pie

  1. Preheat oven to 325°F (160°C). Prepare your 9-inch pie crust.
  2. In a large bowl, beat 4 large egg yolks with an electric mixer until light and pale yellow.
  3. Gradually add 1 (14-ounce) can of sweetened condensed milk, mixing until smooth and well combined.
  4. Stir in 1 cup of freshly squeezed Key lime juice (about 8-10 limes). Mix until fully incorporated.
  5. Pour the lime filling into the prepared pie crust.
  6. In a separate bowl, beat 4 large egg whites until soft peaks form.
  7. Gradually add ½ cup granulated sugar, beating until stiff, glossy peaks form. Add 1 teaspoon vanilla extract.
  8. Carefully spread the meringue over the lime filling, sealing the edges to the crust.
  9. Bake for 25 minutes, or until the meringue is lightly browned and the filling is set.
  10. Let the pie cool completely before serving. Refrigerate for at least 4 hours for optimal flavor.
