If you ever visit the southern states, youll see this pie on every dessert menu. Key Lime is also a pie that any good Southern cook has in their collection of recipes. And for good reason this pie is delicious!

A Key Lime Pie is made up of egg yolks, sweetened condensed milk and key lime juice. No thickening agent is needed in baking this pie. A natural chemical reaction occurs between the egg yolks, key lime juice and sweetened condensed milk, allowing it to thicken on its own. Its baked for a short amount of time in a graham cracker crust.

History of Key Lime Pie:

Roots of this pie have been traced back to the early 20th century in the Key West area of Florida. Exact origins are unknown, but its believed that it may have been concocted by the cook for Key Wests first millionaire, William Curry. In 2006, the Key Lime Pie was voted in as the official pie of the state of Florida! If youre really a fan of the key lime flavor, you can go to the annual Key Lime Festival every year over Fourth of July weekend.

The popularity of key lime pie has spread to the whole southern region of the United States. Its now a beloved favorite.

How to make a Key Lime Pie:

First youll make a simple graham cracker crust. Its a blend of graham cracker crumbs and butter. No need to crush your own graham crackers you can buy a box of the crumbs near the regular graham crackers. The mix is pressed into a pie plate, and then its baked for just five minutes.

The filling is a blend of egg yolks, key lime zest, key lime zest and sweetened condensed milk. The pie is baked for only 15 minutes, and then its refrigerated until its nice and thick and ready for slicing. If youd like to add garnish, add whipped cream and key lime slices.

A note about key lime juice:

If you know anything about key limes, then you know that theyre tiny. If you squeeze them to get juice, youll be squeezing all day long! You need a cup of key lime juice for this recipe. Instead of squeezing fresh limes, I recommend using Nellie & Joes Key West Lime Juice. You can buy it on Amazon, or you should be able to locate it in the juice aisle of a good grocery store.

  2. Pour the filling into the crust and bake for 15 minutes. Refrigerate the pie for several hours (or overnight) before serving. It will thicken more as it chills. Serve with whipped cream and lime slices for garnish.
