Why This Recipe Works
This recipe is designed for simplicity and guaranteed success. Here’s what makes it so effective:
- Simplicity: We’ve streamlined the process, using readily available ingredients and clear, concise instructions. No fancy equipment or complicated techniques required!
- Double Boiler Method (Optional, but Recommended): While you can make lemon curd directly in a saucepan, using a double boiler or a heatproof bowl set over a simmering pot of water provides gentle, even heat. This prevents the eggs from scrambling and ensures a silky smooth curd. If you don’t have a double boiler, we’ll provide instructions for both methods.
- Proper Ratios: The ingredient ratios are carefully balanced to achieve the perfect combination of sweetness, tartness, and richness.
- Constant Stirring: This is key! Constant stirring ensures the mixture heats evenly and prevents scorching or curdling.
- Temperature Control: We’ll guide you through the temperature cues to look for, ensuring your curd reaches the perfect consistency.
Ingredients
- 1/2 cup (1 stick or 113g) unsalted butter, cut into cubes
- 1 cup granulated sugar
- 1/2 cup freshly squeezed lemon juice (from about 3-4 lemons)
- Zest of 2 lemons
- 3 large eggs
- 1/4 teaspoon salt

Instructions
Double Boiler Method:
- Prepare the Double Boiler: Fill a saucepan with about 1-2 inches of water and bring to a simmer over medium heat. Make sure the water doesn’t touch the bottom of the heatproof bowl you’ll be using.
- Combine Ingredients: In the heatproof bowl, combine the butter, sugar, lemon juice, lemon zest, eggs, and salt.
- Cook and Stir: Place the bowl over the simmering water, ensuring it fits snugly. Cook, stirring constantly with a whisk or wooden spoon, until the butter is melted and the sugar is dissolved.
- Continue Cooking: Continue cooking and stirring constantly for about 10-15 minutes, or until the curd thickens enough to coat the back of a spoon. You should be able to draw a line through the curd on the spoon with your finger, and the line should hold. The curd will continue to thicken as it cools. The temperature should reach 170-175°F (77-79°C) if you’re using a thermometer.
- Remove from Heat: Remove the bowl from the double boiler and let cool slightly.
- Strain (Optional): For an extra smooth curd, strain it through a fine-mesh sieve into a clean bowl. This will remove any small bits of cooked egg.
- Cool and Store: Transfer the curd to a clean jar or container. Let it cool completely at room temperature, then cover and refrigerate.
Saucepan Method:
- Combine Ingredients: In a medium, heavy-bottomed saucepan, combine the butter, sugar, lemon juice, lemon zest, eggs, and salt.
- Cook Over Low Heat: Cook over very low heat, stirring constantly with a whisk or wooden spoon. It’s crucial to keep the heat low to prevent the eggs from scrambling.
- Continue Cooking: Continue cooking and stirring constantly for about 10-15 minutes, or until the curd thickens enough to coat the back of a spoon. You should be able to draw a line through the curd on the spoon with your finger, and the line should hold. The curd will continue to thicken as it cools. The temperature should reach 170-175°F (77-79°C) if you’re using a thermometer.
- Remove from Heat: Remove the saucepan from the heat and let cool slightly.
- Strain (Optional): For an extra smooth curd, strain it through a fine-mesh sieve into a clean bowl. This will remove any small bits of cooked egg.
- Cool and Store: Transfer the curd to a clean jar or container. Let it cool completely at room temperature, then cover and refrigerate.
Tips for Success
- Use Fresh Ingredients: Freshly squeezed lemon juice and freshly grated lemon zest will give you the best flavor.
- Don’t Overcook: Overcooked lemon curd can become grainy or curdled. Watch the temperature and consistency carefully.
- Stir Constantly: This is the most important tip! Constant stirring prevents the eggs from scrambling and ensures a smooth, creamy curd.
- Patience is Key: It takes time for the curd to thicken. Don’t rush the process.
- Adjust Sweetness: Taste the curd as it cooks and adjust the sugar to your liking.
- Use a Heavy-Bottomed Saucepan (for Saucepan Method): A heavy-bottomed saucepan helps to distribute heat evenly and prevent scorching.
- Don’t Let the Bowl Touch the Water (for Double Boiler Method): Make sure the bottom of the bowl doesn’t touch the simmering water, as this can overheat the curd.
Storage Instructions
Lemon curd should be stored in an airtight container in the refrigerator. It will keep for up to 2 weeks.
Freezing: While not ideal, lemon curd can be frozen. However, the texture may change slightly upon thawing, becoming a bit thinner. To freeze, transfer the cooled curd to a freezer-safe container, leaving some headspace. Thaw overnight in the refrigerator. Stir well before using.

FAQ
Why is my lemon curd grainy?
Grainy lemon curd is usually caused by overcooking or overheating. Make sure to cook the curd over low heat, stirring constantly, and avoid letting it boil. Straining the curd can also help remove any small bits of cooked egg.
Why is my lemon curd too thin?
Thin lemon curd may not have been cooked long enough. Continue cooking, stirring constantly, until it thickens to the desired consistency. Remember that it will thicken further as it cools.
Can I use bottled lemon juice?
While you can use bottled lemon juice, freshly squeezed lemon juice will give you a much brighter and more flavorful curd. If you do use bottled juice, choose a high-quality brand.
Can I use a different citrus fruit?
Yes! You can adapt this recipe to make other citrus curds, such as lime curd, orange curd, or grapefruit curd. Simply substitute the lemon juice and zest with the juice and zest of your chosen citrus fruit.
What can I use lemon curd for?
Lemon curd is incredibly versatile! Here are just a few ideas:
- Spread on scones, muffins, or toast
- Fill tarts, cakes, or pastries
