  • 1 pinch Salt
  • 1 tablespoon Sugar

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C).
  2. Crush the graham crackers into fine crumbs and mix with melted butter, sugar, and a pinch of salt.
  3. Press the mixture firmly into the bottom of a 9x13 inch baking dish.
  4. Place it into the center rack of the oven for 10 minutes and let it cool.
Filling
  1. Reduce the oven temperature to 325°F (160°C).
  2. In a bowl, whisk together sweetened condensed milk, sour cream, vanilla, lime juice, and lime zest until smooth.
  3. Whisk the egg yolks in a small bowl, then mix in a little of the filling to blend smoothly.
  4. Pour everything back into the main bowl and whisk until creamy and well combined.
  5. Pour the filling over the crust and spread evenly.
  6. Bake in the center rack of the oven for 18-20 minutes or until the center is set but still slightly jiggly.
  7. Let cool completely, then spread the Cool Whip evenly on top.
  8. Garnish with more lime zest and refrigerate for at least 2 hours.

Notes

Serve chilled and cut into squares or wedges. Add a basil or mint leaf for freshness, or sprinkle with crushed toasted coconut for a beachy touch. Store covered in the refrigerator for up to 4 days. Use parchment to separate squares if stacking.
