- For a summer party, make this the night before to save time.
- Try using bottled key lime juice if fresh limes aren’t available.
- Press the crust firmly into the pan to prevent crumbling.
- Add a pinch of salt to the crust to enhance the flavor.
Easy Flavor Ideas

Common Questions
Can I make this pie ahead of time?
Yes, this is a great make-ahead dessert. It actually tastes better after chilling in the fridge overnight. This makes it perfect for busy entertaining days.
What if I can’t find Key limes?
Regular Persian limes work just fine in this recipe. The flavor will be slightly less tart but still very delicious. You will need about three large regular limes.
How do I know when the pie is done?
The edges should look set and stable. The center should still have a slight, jell-o-like jiggle. It will firm up completely as it cools down.
I hope this refreshing pie brings a little sunshine to your table. It is the perfect way to end a summer meal with family. Happy baking!
