This homemade lemon curd recipe is tangy, smooth, and bursting with fresh lemon flavor. Made with whole eggs for a silky texture and a generous amount of lemon juice, it avoids any eggy taste. Perfect for spreading on toast, topping desserts, or baking into your favorite treats, this easy recipe uses simple ingredients like eggs, lemons, sugar, and butter. With no need to temper the eggs, it's a foolproof method that delivers a sharp yet creamy curd every time.
Set up a double boiler by filling a medium saucepan with a couple of inches of water. Bring the water to a simmer over medium heat. Place a heatproof bowl on top of the saucepan, making sure the bottom of the bowl does not touch the water.
In the heatproof bowl, whisk the 6 large eggs and 200g of sugar together until fully combined. The mixture should be pale yellow and slightly frothy. This will ensure the sugar is well incorporated and the curd will be smooth.
Stir in the 240g of freshly squeezed lemon juice, zest of 6-8 lemons, and ¼ teaspoon of fine sea salt. Continue whisking gently to mix everything together. The lemon zest will infuse the curd with more intense citrus flavor, while the salt balances the sweetness.
Place the bowl with the egg mixture over the simmering water. Cook the mixture, stirring constantly with a whisk or silicone spatula to prevent the eggs from curdling. This process can take about 10-15 minutes. Be patient—this slow cooking ensures a smooth and creamy texture.
You’ll know the lemon curd is ready when it thickens and coats the back of a spoon. To test, dip a spoon into the curd and run your finger along the back of it; if the line holds, the curd is done.
Once the lemon curd has thickened, remove the bowl from the heat. While the curd is still hot, slowly whisk in the 113g of unsalted butter, a few pieces at a time, until fully melted and the mixture becomes silky and glossy. The butter adds richness and a smooth texture to the curd.
To achieve a perfectly smooth lemon curd, strain the mixture through a fine-mesh sieve into a clean bowl. This step will remove the lemon zest and any bits of cooked egg that might have formed. Use a spatula to gently push the curd through the sieve.
Once strained, let the lemon curd cool slightly at room temperature. Then, transfer it to a clean, airtight jar or container. Allow it to chill in the refrigerator for at least 2 hours before using. This resting time helps the curd set and develop its flavors further.
