For the Key Lime Filling:
✅ 3 large egg yolks – Helps create a rich and creamy texture.
✅ 1 can (14 oz) sweetened condensed milk – Adds the perfect sweetness.
✅ ½ cup key lime juice – Freshly squeezed for the best flavor!
✅ 1 tablespoon lime zest – Enhances the citrusy taste.

🔬 The Science Behind Its Unique Texture
The magic of Key Lime Pie lies in its simple yet effective chemistry. Here’s why:
- Egg Yolks & Condensed Milk – These ingredients thicken naturally when combined with the acidity from the lime juice. No need for cornstarch or flour!
- Lime Juice – The acidity curdles the egg yolks and milk, creating a thick, smooth, and creamy texture when baked.
- Chilling Time – This allows the pie to set fully, enhancing its creamy consistency and ensuring each slice holds its shape.
This scientific balance gives Key Lime Pie its silky, melt-in-your-mouth texture!
