Key Lime Pie

Happy Key Lime Pie Day! This delicious lime pie is really easy to make because there’s no need to separate egg whites and egg yolks. Instead of egg yolks I used sour cream to create a perfectly dreamy texture to the filling. When there are no eggs in the recipe you don’t need to worry about the eggs overcooking in the oven and making the texture of the filling a bit grainy. So easy and delicious!

This is definitely one of my all-time favourite recipes and it takes me back to the memories from visiting Florida a couple of years ago. An exhibition of my paintings was part of Miami Art Week in 2019 and in addition to enjoying an amazing amount of the best contemporary art in the world I wanted to find the most delicious Key Lime Pie. The first Key Lime Pie recipe was published in a Miami newspaper in the year 1933. Key Limes are from the Florida Keys which are a string of tropical islands near Miami. It was so inspiring to visit the origin of this heavenly pie!

I hope you’ll enjoy this recipe as much as I do!

This recipe has been published in Me naiset -magazine in Finland and it’s originally from my pie baking book.
