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:
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.
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.
If you want to substitute the sour cream for something a little healthier you can go with plain non-fat Greek Yogurt.
If you want to cut some time then yes you can use a pre-made graham cracker crust for this recipe!
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.
