Classic Key Lime Pie Ingredients

A classic key lime pie crust is made with graham cracker crumbs. Although you could try another kind of cookie, I think the graham crumbs are just perfect here. Sometimes you don’t want to mess with the classic recipes!
Key lime juice and zest are the stars of this pie so don’t use the bottled variety! If you can’t get key limes you could use regular limes. There will be a little difference but not too much.
How to Make the Graham Cracker Crust
To make the crust, combine the graham cracker crumbs with brown sugar and melted butter. Press the mixture into a pie dish and bake it in the oven for about 10 minutes.
If you don’t have graham crumbs, you can make your own with graham crackers and a food processor or a rolling pin.
How to Make the Lime Filling
Mix the zest and juice of your limes with the egg yolks, powdered sugar, sweetened condensed milk and sour cream. Once the pie crust is golden you can spoon in this filling. Now bake the pie until it’s set but still slightly jiggly in the middle. Let it cool down then chill it in the refrigerator for a few hours.
Best Key Lime Pie Recipe Serving Ideas
Making a pie from scratch means it not only deserves the best quality ingredients but also the most elegant presentation. You can’t go wrong with some whipped cream as a garnish.
I also love to add some thin lime wedges on top of each slice. Another idea is to sprinkle lime zest over the pie if you don’t have enough fresh limes to make the slices.
Alternatively you could do both. Add the whipped cream next to a lime slice then sprinkle lime zest over the cream. There’s no such thing as too much lime in the best key lime pie recipe! Traditional key lime pie is a true treat and I know it is near the top of my favourite pie list!
Classic Key Lime Pie FAQs
This tasty graham cracker crust pie with sweetened condensed milk and sour cream will keep for 2 or 3 days. It’s best to keep it in the refrigerator wrapped with foil or plastic wrap.
It’s also possible to freeze it for up to about a month. Again, make sure it’s very well wrapped. You don’t want your classic key lime pie to suffer freezer burn!
There’s a bit of a fine balance here. You don’t want to undercook the pie but neither do you want to overcook it! So how do you find that sweet spot when it’s perfectly done?
I find it takes about 15 minutes to cook through. The center should jiggle very slightly when you take it out of the oven. If it jiggles quite a lot it needs more cooking time. Don’t worry about the ‘jiggle’ by the way – the pie will firm up as it cools down. Overcooking it will give the filling a spongy texture which you’ll want to avoid.
First of all, no you don’t have to use fresh key limes. You can still make a tasty lime pie with any variety of lime. However, if you can get key limes, I recommend you use those! Key limes, also known as West Indies limes, West Indian limes or Mexican limes, are smooth, round and small.
They have a more intense flavour than the regular Persian limes grocery stores carries year-round. If you want to make a classic key lime pie from scratch but you can only get regular limes, it will still be delicious!
