Step 1

Preheat oven to 350°.

Step 2

For the crust: Coarsely crush the crackers (you should end up with about 2 1/4 cups). Combine crushed crackers, butter, and sugar in a medium bowl. Stir until well combined and the crumbs hold together when pressed with your fingers. Press the crust mixture into the bottom and up the sides of a 9-inch pie pan. Freeze the crust for 10 minutes. Bake the crust on the middle rack of the oven for 20-25 minutes or until golden brown. Set the crust aside to cool slightly, about 10 minutes.

Step 3

For the filling: Whisk together the sweetened condensed milk, egg yolks, lemon juice, and lime juice until smooth. Pour the filling into the baked crust. Return the pie to the oven and bake until the center of the filling is just set, about 15 minutes. Cool the pie on a wire rack at room temperature for 1 hour, then refrigerate until cold, at least 2 hours or up to overnight.

Step 4

Top the pie with whipped cream (or whipped topping) and citrus slices just before serving.
