What You Will Need To Make Key Lime Pie

Pie Crust

Graham Cracker Crumbs – Store-bought crumbs are great to use. If you want to make a homemade graham cracker crust, use a food processor to quickly crush graham crackers into fine crumbs. 12 full-size crackers should yield about 1.5 cups. (see FAQ’s)

Sugar – Brown sugar or granulated white sugar can be used. I like to use both in the crust.

Melted Butter – Unsalted

Ground Cinnamon – (optional) I think it adds just a little bit of spice to the graham cracker mixture.

Pie Filling

Lime Juice – Fresh Key limes are tiny in size. It takes about 20-25 limes to yield 1/2 cup of juice. I like to use bottled Key lime juice for convenience and can usually find it at a local grocery store. My favorite is Nellie & Joe’s Key Lime Juice, it has an authentic taste and is made with 100% Key West limes

Egg Yolks – Large eggs at room temperature.

Sweetened Condensed Milk – Use regular. I’ve tried fat-free condensed milk in this recipe and the texture is not the same.

Recipe Tips

The crust should be about 1/4 inch thick. I find it easiest to press the sides of the pie first, and then finish by pressing the bottom.

I don’t worry about trying to make the edges even or perfect. Visually the crust looks authentic and it doesn’t make any difference with the taste of the finished product.

Be careful not to overbake the pie, as the filling will continue to set as it cools.

You can use store-bought whipped cream or Cool Whip instead of making fresh whipped cream.

Frequently Asked Questions

What is the difference between key limes and regular limes?

Key limes, also known as Mexican or West Indian limes, are smaller and more aromatic than regular limes. Key limes have a high acidity level and a more intense flavor.

Can I use regular lime juice instead of Key lime juice?

While you can substitute regular lime juice in a pinch, it doesn’t have the intense flavor of authentic Key lime juice. Try to use fresh Key lime juice whenever possible.

You can find bottled Key lime juice at your local grocery store if fresh limes are unavailable.

Can you make graham cracker crumbs without using a food processor?

Absolutely! A food processor makes crushing graham crackers quick and easy but you can achieve similar results by using a resealable plastic bag and a rolling pin.

Simply place the graham crackers in the bag, seal it tightly, and roll the pin over the bag until the crackers become fine crumbs.

Can I make Key lime pie ahead of time?

Yes, you can! Key lime pie actually tastes better when made ahead of time and allowed to chill in the refrigerator for a least a few hours or overnight. It gives the flavors a chance to mesh together for a more delicious pie!

What’s the best way to store leftover Key lime pie?

If you happen to have any leftover pie (which doesn’t happen often in my house), just cover it loosely with aluminum foil or plastic wrap and store it in the refrigerator for up to 3 days. You can also use a pie carrier to store it in if you have whipped cream on the top.

Can I use a pre-made graham cracker crust?

Yes, if you’re short on time a store-bought crust can be used. They are sold already patted into disposable aluminum pie plates and pre-baked.
