Today we're going to share a fantastic lime curd recipe with you! There's nothing like a silky, flavorful fruit curd filling for injecting into cupcakes or sandwiching in between cake layers.

We used this delicious Lime Curd recipe as a filling in our homemade Lime Cake recipe, but keep it in mind for any dessert that would benefit from a flavor boost of refreshing lime flavor (from white cakes to lemon or coconut)!

How to Make Lime Curd

There's more than one way to make a delicious curd filling, but most of our favorite recipes involve combining zest, juice &/or water, sugar, egg yolks, butter, and cornstarch as a thickener.

The ingredients are simple, but the end result is so luscious and indulgent, you'll want to spread it on everything from cakes and sweet breads to your morning toast!

To make the lime curd, we first combined sugar and cornstarch in a saucepan, and add the water. Stirring constantly, we heated the mixture until it began to bubble.

We then spooned part of the hot mixture into a bowl with the egg yolks and stirred to combine. We then added this back to the saucepan.

Once ready, we removed the saucepan from heat and added the butter, lime juice, and lime zest. Allow the lime curd to cool before using!

Why is this Lime Curd Yellow?

The color in curd fillings comes mainly from the egg yolks. This is why most curd fillings are a lovely shade of yellow.

The yellow makes sense when you're making a lemon or pineapple curd, but for lime curd filling, you may have been expecting a shade of green.

You can tint your lime curd with a touch of green coloring gel if you'd like, but I prefer the shade just as it is, speckled with bits of green lime zest.

We hope that you enjoy this recipe as much as we have! If you've never tried a fruit curd filling, you are missing out! They are really easy to make and the taste is just heaven!
