Lemon curd is a luscious, tangy spread that brightens up any dessert or breakfast. Using just five eggs, this recipe creates a silky, flavorful lemon curd that’s perfect for spreading on toast, filling tarts, or topping cakes. It’s simple to make at home, and with a few tips, you’ll achieve a perfectly smooth and vibrant curd every time.
Ingredients
- 5 large eggs
- 1 cup (200 g) granulated sugar
- 1/2 cup (120 ml) fresh lemon juice (about 2-3 lemons)
- 1 tablespoon lemon zest (from about 1 lemon)
- 1/2 cup (115 g) unsalted butter, cut into small pieces
Instructions
- Prepare the lemon zest and juice: Zest one lemon using a fine grater, avoiding the bitter white pith. Juice 2-3 lemons until you have about 1/2 cup of lemon juice. Set aside.
- Combine ingredients in a heatproof bowl: In a medium heatproof bowl, whisk together the eggs, sugar, lemon zest, and lemon juice until well combined.
- Cook the mixture gently: Place the bowl over a saucepan of simmering water (double boiler setup). Make sure the bottom of the bowl doesn’t touch the water. Cook, whisking constantly, until the mixture thickens and reaches about 170°F (77°C), approximately 10-15 minutes.
- Add butter: Remove the bowl from heat and immediately whisk in the butter pieces, one at a time, until fully incorporated and the curd is smooth and shiny.
- Strain for smoothness: Pour the curd through a fine sieve into a clean container to remove any cooked egg bits and zest. This step ensures a silky texture.
- Cool and store: Allow the lemon curd to cool to room temperature, then cover with plastic wrap directly on the surface to prevent a skin from forming. Refrigerate for at least 2 hours before using.
Tips
- Substitutions: For a dairy-free version, replace butter with coconut oil or a neutral-flavored vegan butter. Use bottled lemon juice if fresh lemons are unavailable, but fresh is preferred for the best flavor.
- Storage: Keep lemon curd in an airtight container in the refrigerator for up to 1 week. For longer storage, freeze in small jars for up to 3 months.
- Prevent curdling: Constant whisking and gentle heat are key. Do not rush the process or cook over high heat, as eggs can scramble.
- Make ahead: Lemon curd tastes even better after sitting for a day, allowing flavors to meld. Prepare in advance for desserts or breakfast spreads.
Serving Suggestions
Spread lemon curd on toasted bread, scones, or croissants for a bright start to your day. Use it as a filling for tarts, layered in cakes, or dolloped over Greek yogurt or ice cream for a tangy finish. It also pairs wonderfully with meringue or as a topping for cheesecakes.
Variations
For a twist on the classic, try adding a splash of vanilla extract or a pinch of ginger to the mixture before cooking. You can also infuse the curd with herbs like thyme or basil for an aromatic note. For a berry-flavored version, fold in pureed raspberries or blueberries after the curd has cooled.
Storage and Reheating
Store homemade lemon curd in an airtight container in the refrigerator for up to 1 week. For longer storage, freeze in small jars or ice cube trays for up to 3 months. To reheat, gently warm in the microwave or in a double boiler until smooth and spreadable. Always stir well before serving.
Frequently Asked Questions
Can I make lemon curd without eggs?
Traditional lemon curd relies on eggs for its creamy texture and tangy flavor. However, vegan alternatives using cornstarch or agar-agar are available, but they tend to have a different consistency. For the most authentic experience, eggs are recommended.
How can I tell when the lemon curd is done?
The curd is ready when it thickens enough to coat the back of a spoon and reaches about 170°F (77°C) on a thermometer. It should be smooth, glossy, and hold its shape when lifted. Overcooking can cause curdling, so keep a close eye during the process.
Can I use bottled lemon juice instead of fresh?
While fresh lemon juice provides the best flavor and brightness, bottled lemon juice can be used in a pinch. Just be aware that the flavor may be slightly less vibrant, and you might need to adjust the amount to taste.
What if my lemon curd is too runny?
If your curd hasn’t thickened enough, return it to the double boiler and cook a few more minutes, whisking constantly. Alternatively, you can whisk in a small amount of cornstarch dissolved in water, then cook until thickened, but this may slightly alter the texture.
How do I prevent a skin from forming on the lemon curd?
Once cooled, press plastic wrap directly onto the surface of the curd to prevent air contact, which causes skin formation. Alternatively, store in an airtight container without a lid until refrigerated, then seal tightly before use.
Can I double or halve this recipe?
Yes, the recipe can be scaled up or down. When doubling, ensure you use a larger bowl and double the cooking time slightly. For halving, reduce all ingredients accordingly, but be mindful that cooking times may be shorter.
