Gather your Ingredients
When preparing a recipe with so few ingredients, it's important to focus on quality. Fresh squeezed lemon juice is critical to delicious tasting curd. Don't attempt to make this recipe with bottled lemon juice, which often has preservatives. A citrus juicer, while non-essential, makes juicing the lemons an especially quick process.
Juice the Lemons
Depending on the size of the lemons, you'll need 5 to 6 lemons to get 1 cup of fresh lemon juice. It's a good idea to use a fine mesh strainer to remove any pulp or seeds. This will result in a very smooth curd.
Whisk Together the Eggs, Yolks, and Sugar
In a medium saucepan (preferably one with a heavy bottom), whisk together the eggs, yolks and sugar.
Create a Slurry
In a small bowl, whisk together the cornstarch with a bit of the lemon juice until smooth, creating a slurry. This will prevent the cornstarch from clumping up. Add the slurry as well as the remaining lemon juice to the saucepan.
Cook the Curd
Turn the heat to medium. Continually whisk the curd mixture until it thickens to the consistency of pudding, approximately 10 to 15 minutes. Make sure the whisk hits the bottom of the pan during this process. Once the curd is thick, remove the pan the heat.
Whisk in the Butter
Whisk in the butter, one piece at a time, until the curd is shiny and smooth.
Chill the Lemon Curd
Press plastic wrap directly against the curd to prevent a skin from forming. Place in the refrigerator to chill before serving.
