A Bright and Sunny Kitchen Staple
I used to be incredibly intimidated by the thought of making my own citrus fillings from scratch. I had heard horror stories of scrambled eggs and runny textures, so I always relied on store bought jars for my lemon desserts.

However, one weekend I was determined to master a true, from scratch Lemon curd recipe that would be completely foolproof. After a few trials, I found the perfect double boiler method that yields a thick, glossy, perfectly tart spread every single time without the stress.
Why This Method Never Fails
You are going to absolutely love this recipe because it takes all the guesswork out of the process. Here is why it works so beautifully:
- The Double Boiler Trick: Cooking the mixture over simmering water rather than direct heat prevents the eggs from scrambling.
- Yolks Only: Using only egg yolks rather than whole eggs creates an incredibly rich, velvety texture.
- Butter at the End: Whisking the butter in off the heat ensures the emulsion stays perfectly stable and glossy.
Everything You Need
- 4 large egg yolks: Room temperature. Save the whites for a meringue!
- 2/3 cup granulated sugar: The perfect amount to balance the sharp citrus without making it overly sweet.
- 1 tablespoon fresh lemon zest: Essential for the deep, aromatic citrus oils.
- 1/3 cup fresh lemon juice: Please use fresh lemons, not the bottled juice, for the best flavor.
- 6 tablespoons unsalted butter: Cut into small cubes and softened to room temperature.
- 1/8 teaspoon salt: Just a tiny pinch to enhance all the flavors.
Crafting Your Curd
- STEP 1Fill a medium saucepan with about 2 inches of water and bring it to a gentle simmer over medium heat.
- STEP 2In a heatproof glass or metal bowl that will fit snugly over the saucepan, whisk together the egg yolks, granulated sugar, fresh lemon zest, lemon juice, and salt until completely smooth.
- STEP 3Place the bowl over the simmering water, ensuring the bottom of the bowl does not touch the water.
- STEP 4Whisk the mixture continuously. Do not walk away! Keep whisking gently for about 10 minutes, or until the mixture thickens significantly and coats the back of a spoon. It should read 170 degrees Fahrenheit on a thermometer.
- STEP 5Remove the bowl from the heat immediately. Whisk in the softened butter cubes one at a time, letting each piece melt completely before adding the next.
- STEP 6Place a fine mesh sieve over a clean bowl and press the warm mixture through it using a spatula. This removes the zest and any tiny cooked egg bits, leaving you with a silky smooth texture.
- STEP 7Press a piece of plastic wrap directly onto the surface of the curd to prevent a skin from forming. Chill in the refrigerator for at least 2 hours to thicken completely.
Fun Twists and Serving Ideas
- The Perfect Filling: Use this rich spread as the shining star between the layers of a towering Lemon curd cake.
- Cookie Pairings: Dollop a generous spoonful onto the center of warm Lemon curd cookies for a beautiful, tart finish.
- Breakfast Upgrade: Swirl it into your morning oatmeal, spread it on toasted brioche, or serve it with warm scones.
- Endless Options: Once you master this base, you can use it in dozens of Lemon Curd Recipes, from tarts to trifles to parfaits.

Pro Tips
- Never Stop Whisking: The key to avoiding scrambled eggs is continuous motion. Keep that whisk moving the entire time it is over the heat.
- Watch the Water Level: Ensure the simmering water does not touch the bottom of your mixing bowl. You want gentle steam to cook the eggs, not boiling water.
- Strain It: Even if you think you whisked perfectly, do not skip straining it through a fine mesh sieve. It guarantees that signature velvety texture.
- Use Non Reactive Bowls: Always use a glass, ceramic, or stainless steel bowl. Aluminum or copper bowls will react with the acid and give your spread a metallic taste.
- Patience is Key: It might seem like it is taking forever to thicken, but it will happen. Do not turn up the heat to rush it.

Method
- Fill a medium saucepan with about 2 inches (5 cm) of water and bring it to a gentle simmer over medium heat.
- In a heatproof glass or stainless steel bowl that fits snugly over the saucepan, whisk together the egg yolks, granulated sugar, lemon zest, lemon juice, and salt until completely smooth.
- Place the bowl over the simmering water, making sure the bottom of the bowl does not touch the water. The mixture should cook gently from the steam.
- Whisk continuously for about 10 minutes, or until the mixture thickens significantly and coats the back of a spoon. Check with a thermometer; it should reach 170°F (77°C). Keep the water at a gentle simmer and do not stop whisking.
- Immediately remove the bowl from the heat. Whisk in the softened butter cubes one at a time, allowing each piece to melt completely before adding the next.
- Place a fine mesh sieve over a clean bowl. Press the warm lemon curd through the sieve with a spatula to remove the zest and any small cooked egg particles, leaving a smooth, silky spread.
- Press plastic wrap directly onto the surface of the warm curd to prevent a skin from forming. Refrigerate for at least 2 hours, or until completely chilled and thickened.
Notes
FAQs
How long does this keep in the refrigerator? Store it in an airtight jar in the refrigerator, where it will stay fresh and delicious for up to 2 weeks.
Can I freeze homemade curd? Yes! You can freeze it in an airtight container for up to 3 months. Let it thaw overnight in the refrigerator before using.
Why is my mixture still runny? It needs to reach 170 degrees Fahrenheit to fully thicken. Also, keep in mind that it will thicken significantly more as it cools in the refrigerator.
Can I use whole eggs instead of just yolks? You can, but the texture will be slightly less rich and more gel like. The yolk only method provides the creamiest, most luxurious result.
Why does my batch taste metallic? This happens if you used a reactive metal saucepan or bowl, or if you whisked with an aluminum whisk. Always use stainless steel, glass, or silicone tools when working with high acid ingredients.
