What is Key Lime Pie?
Key lime pie is an American classic dessert starring the sweet/tart, fragrant little key lime that comes from (you got it!) the Florida Keys. Also known as Mexican or West Indies limes, key limes are smaller, more yellow than green, and extra tart compared to regular limes.
The pie was created by a cook named Aunt Sally from a custard of egg yolks, sweetened condensed milk, and a liberal amount of lime juice baked into a crust and served with a dollop of whipped cream, best served cold. No Florida vacation is complete without treating yourself to a big slice of Aunt Sally’s famous Key Lime Pie!

Ingredients and Variations
CRUST: Graham cracker crusts are so easy to make and so versatile! For more flavor, add some ground pecans or walnuts to the mixture. In a pinch for time? Simply use a pre-made graham cracker crust.
FILLING: For the best results, use key lime juice for its superior flavor and aroma compared to regular lime juice. They’re worth the extra squeezing to get out every juicy drop for this pie. Otherwise, add some lime zest to the filling for that bright citrus flavor. Extra-large eggs will produce a fluffier pie and will be easier to whisk when they are used at room temperature.
