Key Lime Pie

Most people think of Key West, Florida when they have Key Lime Pie. The pie was made famous by and originated in the Keys, where Key limes were a plenty. I’m going to show you how to make luscious, creamy Key Lime Pie in your own kitchen.

Why this recipe works

There are a few theories about how this sweet-tart cream pie came to be. One of the oldest stories comes from the 1800’s and tells of Bill Curry, Florida’s first self-made millionaire. Bill’s “Aunt Sally” used to make the pie for him. However, historians don’t think Sally created it, but rather adapted a recipe created by local fisherman.

Fast forward to 1930 when the Overseas Highway was built. Prior to that the Keys did not have refrigeration, and therefore no way to store milk. Instead cooks depended on sweetened condensed milk for many of their dishes. You guessed it… including Key Lime Pie!

If you’ve ever been to Key West you know you can find treats of the Key Lime Pie variety at shops all over town. When I was in Key West a few years ago, my kids and I stopped in to Kermit’s Key West Key Lime Shoppe. You can buy pie, pie bars, candy, jellies, and more. It’s a definite must visit attraction while visiting. But let’s move on to making our own Key Lime Pie so you don’t have to fly to Florida, shall we?

GRAHAM CRACKER CRUMBS – You can grind them in a food processor, smash them in a zipper plastic bag, or buy them in crumb form.

BUTTER – You’ll need melted butter, salted or unsalted is fine.

LIME JUICE – You will need about a dozen Key limes to get 1/2 cup of juice because Key limes are only about the size of a golf ball. Please don’t use regular limes, you will insult the entire state of Florida! Alternatively, you can use bottled key lime juice if you can find it at your grocery store.

GARNISH – Lime peel strips make a really pretty garnish. It’s easiest to peel the strips off before juicing the limes. You could just use lime zest if you prefer.
