Lemon Curd is one of my favorite classic desserts, an easy, one-bowl recipe that simmers gently over a double boiler until thickened. That’s it!
Bring a saucepan of water to a gentle simmer and set a glass or metal bowl over the top to create a double boiler. In the bowl, whisk together eggs, yolks, sugar, butter, lemon zest, and lemon juice.
Cook over the simmering water, stirring frequently, until very thick, about 20 to 25 minutes (the curd must reach 170 degrees on a thermometer to thicken).
Strain through a fine-mesh strainer or cheesecloth, then cover and chill completely.
