Key Lime Pie Ingredients

So what is Key Lime Pie filling made of?

Well, you’ll just need a few simple key lime pie ingredients to make your own delicious, creamy homemade pie filling!

Add the following to your next grocery list, so you’ve got all the ingredients on hand…

• Graham Cracker Pie Crust – homemade graham cracker crust can be substituted
• Key Lime Juice – now you can make this all year long!
• Sweetened Condensed Milk – to sweeten up the pie filling
• Sour Cream – to thicken up the pie filling
• Grated Lime Zest – it adds such a tasty punch of flavor!
• Sea Salt – to bring out the flavors
• Whip Cream or Cool Whip – for topping

Don’t forget to have some cool whip or whip cream on hand for topping, too.

It will INSTANTLY take your pie to the next level!

Then, if you’re feeling fancy, you can even add some little slices of lime to the top center of the pie.

It adds such a pretty little pop of color!

Can I Substitute Regular Lime Juice for Key Lime in a Pie?

Wondering if you can use regular limes instead of key lime juice?

Yes, equal portions of fresh squeezed lime juice and fresh squeezed lemon juice can be substituted for the key lime juice.

Just note, the flavor of the pie will be slightly less tart and tangy than a traditional key lime pie.

So for example, in this recipe you would use…

6 tablespoons Fresh Squeezed Lemon Juice

6 tablespoons Fresh Squeezed Lime Juice

I would still recommend using the full tablespoon of grated lime zest, though.

It adds such a delicious punch of flavor to this pie!

What Causes a Key Lime Pie to Thicken?

The secret for a perfectly thick key lime pie is the combination of Sweetened Condensed Milk and Sour Cream.
