After wandering through an antiques store in Little Mountain, South Carolina, I managed to emerge with only three vintage cookbooks. This, truth be told, was nothing short of a miracle. As it turns out, there are a lot of antique cookbooks to be had here, which, as a newcomer, I found terribly hard to resist…somewhere within those volumes was an authentic, handed-down Southern key lime pie recipe!
I leafed through the recipes hungrily, looking for different culinary influences in the ingredients which might have contributed in some way to southern cooking’s unique charm. I suspected to encounter a lot of butter and refined sugar–and it’s true, those ingredients were star players on many of the pages–but I was excited to see ingredients more on the “earthy” side, like turnips, greens, root vegetables, and grains.
Colonialist ingredients clearly do not stand on their own, in this cuisine: the more “rooted” ingredients add a lot of richness to a well-rounded palate, much fuller than the myopic view fast food chains would lead us to believe.
Authentic Southern Key Lime Pie
When I saw a tantalizingly simple recipe for key lime pie, I figured I’d best give it a shot. I’m trying to pinch my pennies right now, after all. The South is a pretty good place to do this; plus, freshly made key lime pie makes it easy to forget one is doing so.

This was a great excuse to break in my new food processor, besides…blitzing the sleeve of graham crackers was delightfully easy, and made perfectly uniform pieces.

This recipe was dead simple. Only a handful of ingredients, and just a few steps. The hardest part was waiting for the pie to chill…

Because you need whipped cream on a key lime pie, I added a few finishing touches, and…voila! Will definitely be eating this for breakfast until it’s gone…

Southern Key Lime Pie
Ingredients
Crust
- 1 sleeve graham crackers
- 6 Tbs butter melted
- 1 pinch finely ground salt
Filling
- 2 14 oz cans sweetened condensed milk
- 6 egg yolks
- 1 cup freshly squeezed lime juice
- 3/4 cup heavy whipping cream
- 1/4 cup powdered sugar
Instructions
- Preheat oven to 350°F.
- Blitz graham crackers in a food processor or blender until they are uniform in texture and size. Add melted butter and salt and combine until the mixture resembles coarse sand.
- Press graham cracker mixture into a 9-inch pie dish until it is evenly dispersed in a thin layer across the bottom and up the sides.
- Bake for 7 minutes, or until the tops of the crust are golden brown and releasing a pleasant aroma. Cool at least 30 minutes.
- Meanwhile, beat sweetened condensed milk, egg yolks, and freshly squeezed lime juice in a medium bowl with a whisk until combined. Pour the mixture into the cooled pie crust. Zest fresh lime peel evenly over the top of the custard mixture, and chill at least two hours.
- Before serving, whip cream and powdered sugar in a deep bowl and beat with an electric mixer. Using either a piping bag or a spoon, place 12 dollops of cream around the edges of the surface of the pie in a circle, then one dollop for the middle. If desired, zest more lime peel over the top. Serve immediately.
