Ingredients
  

  • 1 1/2 cups Graham cracker crumbs finely crushed
  • 6 tablespoons melted butter
  • 1 can (14 oz) sweetened condensed milk
  • 1/2 cup fresh lime juice about 4-5 limes
  • 4 large egg yolks lightly beaten
  • 1 teaspoon lime zest from about 2 limes
  • Pinch salt

Equipment

  • Mixing Bowl
  • 9-inch pie dish
  • Whisk
  • measuring cups and spoons
  • Food processor or plastic bag and rolling pin
  • Baking sheet

Method
 

  1. Combine graham cracker crumbs and a pinch of salt in a mixing bowl, then pour in melted butter. Mix until the crumbs are evenly coated and hold together when pressed.
  2. Press the crumb mixture firmly into the bottom and up the sides of a 9-inch pie dish, creating an even crust. Use the bottom of a glass to smooth and compact the crust.
  3. Bake the crust in a preheated 350°F (175°C) oven for 8-10 minutes until fragrant and slightly golden. Remove from oven and let cool while preparing the filling.
  4. In a mixing bowl, whisk together egg yolks and lime zest until smooth and slightly pale in color. This helps incorporate air and develop flavor.
  5. Add sweetened condensed milk to the egg yolk mixture and whisk until fully combined, creating a creamy, thick filling base.
  6. Pour in the fresh lime juice gradually, whisking constantly until the mixture thickens slightly and becomes smooth. The filling will turn a pale green and have a slightly pudding-like consistency.
  7. Pour the lime filling into the cooled crust, smoothing the top with a spatula for an even surface.
  8. Bake the pie at 350°F (175°C) for 12-15 minutes, or until the edges are set but the center still jiggles slightly when gently shaken. Feel the slight wobble—this indicates perfect doneness.
  9. Remove from the oven and let cool to room temperature. Then, cover loosely with plastic wrap and refrigerate for at least 4 hours or overnight to fully set and develop flavors.
  10. Slice the chilled pie with a sharp knife, revealing the vibrant lime custard and crisp crust. Serve plain or with a dollop of whipped cream if desired.

Notes

For an extra burst of lime flavor, sprinkle a little additional lime zest on top before serving. To make the crust gluten-free, substitute graham crackers with gluten-free digestive biscuits and adjust baking time as needed.
