Instructions
Step 1: Make the Crust
- Preheat oven to 350°F (175°C).
 - Mix graham cracker crumbs, sugar, salt, and melted butter until combined.
 - Press evenly into a 9-inch pie dish.
 - Bake for 8-10 minutes, then let cool.
 
Step 2: Make the Filling
- Whisk sweetened condensed milk, lime juice, zest, and egg yolks until smooth.
 - Pour into cooled crust.
 
Step 3: Bake or Chill
- For a firmer pie, bake at 350°F for 10-12 minutes (center should jiggle slightly).
 - No-bake option – Chill for at least 4 hours without baking.
 
Step 4: Chill & Serve
- Refrigerate for at least 4 hours (overnight is best).
 - Serve cold, topped with whipped cream and lime zest.
 
Pro Tips:
✔ Soggy crust? Pre-bake longer and let it cool before adding the filling. ✔ Filling too runny? Add egg yolks or bake briefly, then chill longer. ✔ Swap key limes for Persian limes—adjust sugar to taste.
