Key lime pie is famous for being Florida’s official state pie as it was declared so in 2006 by the Florida legislature.

You can even make them in your kitchen!

If you haven’t had key lime pie before, I bet you would want to know what is so special about this pie. What does key lime pie taste like, and why is it so good that it is named a state’s official pie? Let us see (or, in this case, read) for ourselves, shall we?

What does key lime pie taste like?

A well-made key lime pie taste like something out of this world, so yummy that you’d want to have a second helping. With a crunchy crust and a sweet, tangy, and citrusy filling that perfectly blends with the sweetness and tanginess of key lime and the sweetness of condensed milk, key lime pie tastes so good that it has retained its position as Florida’s official state pie.

If you don’t know what key lime pie taste like, I suppose you have never eaten key lime pie before. Well, the pudding taste is in the eating. 

What is key lime pie?

Key lime pie is named after small aromatic limes, known as key limes, which are native to the Florida Keys, a group of tropical Islands located off the southern coast of the state of Florida, United States of America. Unlike the regular Persian limes, which are more common, key limes are yellow when ripe, smaller, and more aromatic.

Key lime pie is an American dessert, usually made up of graham cracker crust (in some cases, pastry crust or no crust at all) and a custard filling that consists of egg yolks, key lime juice, and sweetened condensed milk. Key lime pie filling is usually yellow, not only because key lime juice is yellow but mostly because of the egg yolks added. 

In the past, key lime pie filling was made similar to magic lemon cream pie; this involved mixing all the ingredients thoroughly without cooking, making the egg proteins react with the lime juice acids and condensed milk. Without baking, the mixture curdles and thickens.

However, key lime pies are usually baked in recent times to pasteurize the eggs and further thicken the filling. While you can serve key lime pie without topping, you can also top it with a meringue topping (prepared using egg whites) or whipped cream, if you want.

Also, some people use the regular limes in the absence of key limes, but of course, they’d be missing out on the signature tart but sweet key lime flavour that gives the key lime pie its uniqueness.

Earlier, I promised to share a fail-proof recipe for key lime pie that you can try out. Here it is:


  • 10-12 pieces of graham crackers (for the crust)

  • 5 tablespoons melted unsalted butter (to add moist to the graham crackers, as this will make it easier to press tightly into the pie dish’s bottom)

  • ¾ cup key lime juice

  • 1 tablespoon freshly grated key lime zest

  • 2 large egg yolks

  • 2 cans of sweetened condensed milk

  • ¼ cup powdered brown sugar (optional)

  • 2 cups whipped cream


  • Preheat the oven to 3500F
  • Make the key lime pie crust** 
  • Grind the graham crackers to a smooth, fine texture. You can use a food processor, which will work best to give fine crumbs.
  • The graham crackers must be finely ground as it will make your crust pack together more tightly, reducing the chance for crumbling and cracking.
  • Transfer your cracker crumbs into a medium-sized bowl, add powdered brown sugar (if you like) and melted butter, and then combine thoroughly with your fingers until it feels very pliable.
  • Press the crust tightly into the centre and up the sides of a pie dish. The crust should be about a quarter or half an inch thick. Bake for 8 minutes, remove and set aside to cool.
  • Prepare the filling
  • Combine the key lime juice, key lime zest, sweetened condensed milk, and egg yolk in a bowl.
  • Whisk the mixture thoroughly for 3-5 minutes. Pour the filling on the graham cracker crust and bake for about 15 minutes until the edges appear set. When fully baked, the filling will be jiggly and moist.
  • After baking, let the pie rest for an hour. Then, cover the pie loosely with foil and refrigerate it for about 2-3 hours before serving.
  • Top with whipped cream, key lime zest, and key lime slices as you desire. Cut your key lime pie into slices and serve.

How long to refrigerate key lime pie?

You can refrigerate your key lime pie for three days. However, as it does not contain preservatives, key lime pie should be consumed within three days of preparation while stored in the refrigerator for the duration.

Ensure that your key lime pie does not come in contact with other foods in your refrigerator, as that could make it go bad quickly.

Can you freeze key lime pie?

Yes, you can freeze key lime pie. Frozen key lime pie will remain safe for consumption for up to three months, provided you store it in a freezer bag or an airtight container.

How long can key lime pie sit out?

Key lime pie can sit out for only two hours at room temperature. However, do not let your pie sit at room temperature for more than two hours, as pathogenic bacteria proliferate rapidly at temperatures between 40°F and 140°F (room temperature falls within this range).

Therefore, you should discard your key lime pie if you have left it at room temperature for more than two hours.

You must try key lime pie if you love sweet desserts like me. Key lime pie tastes like nothing you have ever had. So cool and refreshing on a hot day- it’s a perfect summer treat for you and your family. I can’t wait to hear how yummy your key lime pie tastes if you make it this summer!
