1. Preheat oven to 350 degrees. Zest and juice the limes. Add condensed milk and egg yolks. Whisk together until well combined. Let stand to thicken while you prepare the crust.

3. Pour filling into pie shell. Bake for 10-15 minutes, or just until center is set but still jiggly. Refrigerate for at least 3 hours before serving.
