Creamy Key Lime Parfait Recipe

I created this recipe for #SummerDessertWeek! I was sent samples by some of the sponsor companies but as always opinions are 100% mine.

Why Make This Recipe?

Y’all I’m pretty thrilled with this dessert! You really cannot go wrong with this Key West trifecta of flavors:

• key lime
• Graham crackers
• meringue

And this lime curd? It is the best. It’s enriched with some sour cream and white chocolate, giving it a lovely milky flavor that rounds out but doesn’t cut out the sharp citrus.

The Graham crumbles are wonderfully flavorful, because I start with homemade Graham crackers. The touch of cinnamon and mellow nuttiness of the crackers is the perfect foil for the tart key lime curd.

And last, the key lime flavor carries through in the meringue, because there’s a touch of key lime juice in it!

How To Make Key Lime Parfaits

As with all parfaits, there are a few components to make.

You’ll be making key lime curd, Graham cracker crumbles, and key lime Swiss meringue.

None are too hard to make, and I will share some shortcuts you can take in a bit.

Pastry Definition: like a custard, a curd is an egg-thickened sauce made with citrus juice or other tart fruit juice like passion fruit or raspberry.

What You’ll Need

Here are the ingredients you’ll need to make the components:

• key lime juice: provides the main flavor, tartness and liquid for making the curd
• granulated sugar: this recipe contains a lot of sugar. It’s needed to balance the tart juice
• eggs: adds emulsifiers, protein and liquid. I always use large eggs
• egg yolks: adds additional emulsifiers and fats for a smooth mouthfeel
• butter: adds richness
• sour cream: slightly mellows and rounds out the tart citrus juice
• white chocolate: adds additional milky sweetness and lends body once the curd is chilled

These are the ingredients you’ll need to make the Graham cracker crumbles:

These are the same ingredients you’d use to make actual Graham crackers.

The only difference is that rather than forming a cohesive dough and rolling it into sheets, you just cut in the butter and honey until you get a streusel-like consistency.

• Graham flour
• all purpose flour
• brown sugar
• baking soda
• cinnamon
• fine sea salt
• honey
• butter

And for the meringue:

• egg whites
• sugar
• key lime juice
• fine salt

Procedure

For the Lime Curd

Curds are actually easy to make. Regardless of what flavor you are making (lemon curd, key lime curd, passion fruit curd, etc), they all follow the same method.

1. Cook key lime juice, sugar, eggs, and yolks together until the mixture thickens but doesn’t boil
2. Strain into a bowl with the butter, sour cream, and white chocolate
3. Whisk until smooth
4. Chill and serve

For the Graham Crumble

Think of this as making a streusel, but with Graham cracker ingredients:

1. Whisk together the dry ingredients
2. Add pieces of butter and the honey
3. Blend it together with clean hands
4. Spread on a prepared cookie sheet
5. Bake until crisp

For the Swiss Meringue

Swiss meringue is a pretty easy meringue to make. It does go more quickly with a stand mixer, but you can also get good results with a hand mixer.

Here’s the easy how-to:

1. Place the egg whites, sugar, and key lime juice in the bowl of your stand mixer or a metal bowl
2. Bring about an inch of water to a boil in a pot.
3. Turn the heat down to a high simmer, and put the bowl on top of the pot, making sure the bottom of the bowl doesn’t dip down into the water.
4. Whisk constantly until the whites reach 165F to make sure the whites are cooked.
5. Place the bowl on your stand mixer (or use your hand mixer) and whip with the whisk attachment until cool, thick, and billowy.
6. Your Swiss meringue is now ready to use.

PRO TIP: You can freeze Swiss meringue right in a piping bag for a week or two. Pull it out an hour or so before you need it so it softens and is pipeable.

How Long Does Key Lime Curd Last?

Generally, these creamy key lime parfaits don’t last long enough to worry about it, but if you want to make the components ahead and then assemble them all at once, the curd will keep in the fridge just fine for 3 or 4 days.

Can I Take Any Shortcuts to Make These Parfaits?

Absolutely.

• Instead of making your own Graham crackers, you can start with store-bought Graham crackers, grind them up along with some butter and then bake as crumbles as you would if you were making a crumb crust.
• Instead of topping the parfaits with Swiss meringue, feel free to top them with whipped cream or even whipped topping if you’d like.

I do ask that you make this lime curd as written, though.

Most of the store-bought curds I’ve had taste like Pledge, and that’s not a desirable quality in a dessert.

And if you’ve never had curd, lime or otherwise, with white chocolate and sour cream whisked in, you are really missing out! And that ends today.

A Note About Measurement

NOTE: Most of my recipes are written by weight and not volume, even the liquids.

Even though I try to provide you with volume measurements as well, I encourage you to buy a kitchen scale for ease of measuring, accuracy, and consistency.

Especially when making the Swiss meringue, which is based on the weight of the whites, you really do need a kitchen scale.

This is the scale I use, love, and recommend.

Alright, enough talk. Let’s make these key lime parfaits, shall we?

Thank you for spending some time with me today.

Enjoy the key lime parfaits!

Take care, and have a lovely day.
