A DELICIOUS SUMMER PIE RECIPE

I absolutely adore a Homemade Key Lime Pie, there is something about the yin and the yang of tartness and sweetness that makes a key lime pie work. You gotta get the balance just right though! I have been making this pie for years now since visiting Key West. I taste-tested a lot of pies in Key West to come up with (what I think) is the perfect Key Lime Pie recipe! This pie is sure to get eaten fast when you serve it!

FREQUENTLY ASKED QUESTIONS:

How do I tell the difference between a lime and a key lime?

Not every produce department carries key limes. If they do, they will usually have a sign with the name of the fruit so it’s easy to identify. However, you can tell the difference between the two because key limes are smaller than limes. They sometimes have a lighter color than regular limes as well.

Can I use bottled lime juice?

Fresh really is best here. There truly is nothing like it and because it is the star of the show, you want it to have the most authentic flavor and bottled juices just don’t give you that. If you can’t find key limes, then just go with regular limes. It will still taste much better than bottled lime juice.
There is bottled key lime juice that you can buy (made by Nellie & Joe) that you could use if you really insist. Again, I’ve tasted it and don’t really love it. I would rather use fresh limes if I couldn’t find key limes.

Can I substitute the sour cream?

If you want to substitute the sour cream for something a little healthier you can go with plain non-fat Greek Yogurt.

Can I use a pre-made graham cracker crust?

If you want to cut some time then yes you can use a pre-made graham cracker crust for this recipe!

Does this pie have to chill?

Yes. To get the right texture and for it to set up properly, you will want to chill your Key Lime Pie for at least 3 hours.

How do I store?

Stored covered with plastic wrap, Key Lime Pie will keep for up 2-3 days in the refrigerator. This can also be frozen. Cover tightly with plastic wrap and foil and it will keep for up to 1 month. To defrost just remove to the refrigerator overnight.

  1. I cannot find key lime. Can I use regular lime? Someone gave me a piece and my grandson loves it. I want to make it for him and surprise him with it.

    1. You can, it just won’t have that signature tartness that you get with a traditional key lime pie. You could try adding a smidge of grapefruit juice to try and replicate that but to be honest, I’ve never done it.
