Authentic Key Lime Pie Recipe
Everyone has a favorite dessert from a restaurant and no one can usually make it at home and exceed that food memory. My husband is a traveler and a foodie. He eats key lime pie wherever he goes and believes he knows what an authentic key lime recipe should taste like.
I’ve tried my best to recreate a recipe for an authentic key lime pie, one that has the brightness and intensity of limes, the heavenly textures of a thick lime cream paired with an airy light whipped cream and a flavorful, crunchy crust.
How’s that for a classic dessert?
I have over 800 recipes and I want you to know that I fret about them being right for you. It’s my desire for you to have a great experience in your kitchen. So as we argued about texture, I remade the pie, and even came up with a gluten free crust as an option. I’m eating gluten free now, which is not easy, and hope to be bringing you more delicious gluten free dishes, and a post on why I’m doing this. It has nothing to do with trends, but is a health matter.
On my second go round I thought to myself, why can’t everyone be happy? I can make small tarts and vary the crust between traditional graham crackers and an almond flour gluten free option.
The first pie was just a little too thick, so I added more lime juice. I also used a mixture of key limes and Persian limes. If you have a choice between the two, however, I would just go with regular limes because otherwise you will need 25-30 key limes.
Key limes aren’t juicy enough, but they are more tart and that’s what an authentic key lime pie recipe has to have. It has to be tart, but the tartness will be offset by the sweetened condensed milk and the combination is creamy heaven.
Have you ever wondered what sweetened condensed milk is? It’s milk and sugar with the water evaporated out so it’s sticky, rich and whatever you do, do not look at the calorie count.
How to Top the Key Lime Pie
You could top your key lime pie with meringue like Southern Fatty did, or go with my preferred method, and top it with a stabilized whipped cream. The whipped cream can be applied and refrigerated and it will look just as good two days later. I show you how to do that in this video. You can also freeze the pie or small tarts before applying whipped cream. Take out 20 minutes prior to serving. They will taste just as good.
