8 whole graham crackers broken into pieces (use Gluten Free graham crackers to make this recipe Gluten Free)
5 Tablespoons unsalted butter melted and cooled
3 Tablespoons granulated sugar

Whisk 4 large egg yolks and 4 teaspoons grated lime zest together in a medium bowl until the mixture has a slight green tint, about 2 minutes. Add 1 14 ounce can sweetened condensed milk and whisk until smooth. Whisk in ½ cup lime juice. Cover and set aside at room temperature for 30 minutes, until thickened. While you're waiting, prepare the crust.
Move oven rack to middle position and heat oven to 325°F. Pulse 8 whole graham crackers in food processor until they are fine, even crumbs. Add the melted butter and 3 Tablespoons granulated sugar and process until the mixture resembles wet sand. Transfer the graham cracker mixture to a 9-inch pie plate. Press firmly onto the bottom and sides of the pie plate with the palms of your hands or the bottom of a dry measure. Bake for 13-16 minutes until the crust is fragrant and starting to brown.
Once the filling has thickened, pour it into the crust while the crust is still warm. Bake until the edges are firm but the center still jiggles when shaken, about 15 minutes. Cool on a wire rack at room temperature for about an hour, then cover loosely with plastic and refrigerate until filling is chilled, about 3 hours. Garnish with lime slices, additional grated lime zest, or whipped cream as desired.
