Why this recipe works

Lemon Curd is silky lemony goodness. Smooth, tart, sweet, and creamy at the same time, its bright flavor is great spread on scones at an afternoon Tea.
Unfortunately, it can also be fairly pricey in the market, especially if it’s made with real, wholesome ingredients. Luckily, homemade lemon curd is very easy to make, and it only takes four simple ingredients.
Plus, it's a perfect way to use up leftover egg yolks. Perfect if you've been making egg white recipes like French macarons or marshmallows.

What you need
Lemon curd is very easy to make, and it only takes a few simple ingredients: egg yolks, sugar, lemons, and butter.
You'll need the lemon juice and zest for this recipe. A microplane grater and citrus juicer makes quick work getting the lemons ready.
How to Make Lemon Curd
The process is simple: whisk the yolks with sugar, melt in butter, add lemon juice and zest, then cook until thickened. The whole thing takes less than 30 minutes to cook, then chill for an hour or so.
Step 1: Heat Egg Yolks, Sugar, and Butter
Whisk the egg yolks and sugar in a heavy bottomed saucepan over medium-low heat. Add the butter and heat slowly until the butter melts (photo 1).
Step 2: Add Lemon Juice and Zest
Add the lemon juice and zest to the egg yolk mixture (photo 2).
Step 3: Cook until thickened
Cook and stir occasionally until the curd has thickened and coats the back of a spoon, about 10 to 15 minutes (photo 3). Try not to let the mixture boil.
Step 4: Cool
Remove the pan from the heat, put the lid on it, and let it cool to room temperature. The curd will thicken further as it cools, so that's a good time to check its consistency (photo 4). If it seems too thin, see the FAQs below on how to fix runny lemon curd.
When the curd has come to room temperature, transfer it to a clean container with a tight fitting lid (photo 5).

Is your lemon curd too thin after you've chilled it? It could be that you didn't cook it long enough. There are two possible solutions for how to fix runny lemon curd that I've tried, and both require you to reheat it over medium-low heat, stirring constantly, before proceeding with these add-ins.
Method #1: Stir in an egg yolk mixed with 2 tablespoons water to the warmed curd, and cook, stirring constantly, until the curd has thickened and leaves a trail on the back of a spoon.
Method #2: Mix in a slurry of 1 tablespoon cornstarch mixed with ¼ cup water in 1 tablespoon increments to the warmed curd. Stir for a few minutes to see if the curd has thickened enough before adding in more slurry.
Pro Tip: Using Lemon Curd in Recipes
The bright lemon flavor really shines, balanced by a smooth, creamy texture. Served next to scones or toast, it’s a delicious spread on its own. And you can use it for so much more!
Bake cheesecake with lemon curd, or use it as a filling for cakes, trifle, or tarts. Mix it with unsweetened whipped cream for a quick lemon mousse.
You can even fingerpaint on a plate with the kids. Have fun with it!
You can use this same homemade lemon curd recipe using different citrus: limes (regular or key lime), Meyer lemons, oranges, or grapefruits. You'll just need to adjust the amount of sugar based on how sweet and/or tart you want the finished curd to be.
Alongside the recipes for making cream scones and clotted cream, you now have everything you need to go forth and have a lovely afternoon Tea.
