The History of Key Lime Pie
There's some uncertainty about the origin of the beloved Key lime pie. While one camp argues it was created in Key West, Florida in the late 19th century, there are also references to the Borden condensed milk company in New York City in 1931, which published a custard pie recipe nearly identical in makeup to Key lime pie using lemons in the place of limes.
No matter where it originated, Key lime pie typically consists of a graham cracker crust and a condensed milk and Key lime-based custard; often topped with whipped cream or meringue.
Key limes can be tough to come by, depending on where you live. You’ll find that they have different characteristics than the limes you’re used to, with a thinner skin, yellowish color, and more acidic and aromatic flavor profile than standard, Persian limes.
What if I Can't Find Key Limes?
While Key limes are imported from Mexico and Central America, Florida Key limes are only available locally, and are a bit harder to come by. Florida Key limes haven't been grown commercially since 1926, when a hurricane destroyed commercial lime crops in the area.
If you can’t find the real deal, substitute the juice with fresh lime juice—just don't tell any Floridians— or a combination of lime and lemon for a more complex flavor profile. Garnish with sliced Persian limes for a similar presentation, or switch it up with toasted coconut.
Ingredients for Mini Coconut-Key Lime Pies
To make these pies, you'll need:
- Graham cracker crumbs: For the classic crust flavor and texture.
- Sweetened flaked coconut: A surprise addition to the crust, which adds great flavor and a good chewiness.
- Butter: Helps hold the crust together and bake up beautifully.
- Sugar: Also helps hold the crust together.
- Sweetened condensed milk: The creamy, sweet base of the pie filling.
- Key lime juice: Or use a mixture of regular lime and lemon if you can't get Key limes.
- Egg yolks: Boosts the creamy, rich flavor of the filling.
- Salt: A pinch of salt helps balance the tart citrus and sweetness.
- Lime zest: Adds a wonderful floral lime flavor without the zing of juice.
- Heavy cream: Fluffy and light whipped cream is the perfect topper to these mini pies.
- Vanilla: A necessary baking ingredient that rounds out all the flavors of the pie.
- Key lime slices: For garnishing.
Tip for Juicing Key Limes
Key limes are small and can be a chore to squeeze, but microwaving them for 15 seconds will help them soften and juice more easily.
One pound of fresh Key limes will yield about a half cup of juice. If you're using bottled juice, make sure it is 100 percent pure Key lime juice and not sweetened. Our Test Kitchen recommends Nellie and Joe's.

Frequently Asked Questions
-
These pies are ready when the filling has only a very slight jiggle. If there's a real wobble going on, err on the side of caution, and leave them in for a few additional minutes. Be sure to chill thoroughly to give the filling time to set up before serving.
-
Key lime pie is best served chilled, especially after topping with whipped cream. If you need to let the pies sit at room temperature while serving, leave them out no more than 2 hours before popping them back in the refrigerator.
-
If you aren't a big fan of coconut, note that it's only present in the crust (not the filling) of these tarts. You can skip it entirely and go with a traditional graham cracker crust if preferred.
