Classic Zesty Lemon Curd
This recipe produces a silky, stable curd that is far superior to anything youโll find on a grocery store shelf.
Prep time: 10 minutes
Cook time: 10โ15 minutes
Servings: Makes about 1.5 cups (approx. 24 tablespoons)
Ingredients
4 Large Egg Yolks (provides the rich, yellow color and thick structure)
2/3 cup (135g) Granulated Sugar
1/3 cup (80ml) Fresh Lemon Juice (approx. 2โ3 lemons)
1 tbsp Lemon Zest (finely grated)
1/4 tsp Salt
6 tbsp (85g) Unsalted Butter, cubed and at room temperature
Instructions
Create a Double Boiler: Fill a medium saucepan with 1โ2 inches of water and bring to a simmer. Place a heat-proof glass or stainless steel bowl over the pan (ensure the bottom of the bowl doesnโt touch the water).
Whisk: Add egg yolks, sugar, lemon juice, zest, and salt to the bowl. Whisk constantly.
Thicken: Continue whisking for about 10 minutes until the mixture thickens. It should coat the back of a spoon and reach a temperature of $170^\circ\text{F}$ ($77^\circ\text{C}$).
Enrich: Remove the bowl from the heat. Whisk in the cubed butter one piece at a time until completely melted and smooth.
Strain (Optional but Recommended): Pour the curd through a fine-mesh sieve into a jar to remove any bits of cooked egg or zest for a perfectly smooth finish.
Chill: Place plastic wrap directly on the surface of the curd (to prevent a โskinโ from forming) and refrigerate for at least 3 hours. It will thicken significantly as it cools.
Description & Notes
-
Flavor Profile:ย A high-impact balance of sharp acidity and creamy sweetness.
-
Texture:ย Thick enough to hold its shape on a spoon but melts instantly on the tongue.
-
The โMetalโ Rule:ย Never use a reactive aluminum pot or whisk; the acid in the lemon can react with the metal, giving your curd a metallic taste and a dull grey tint.
Pro-Tips for Success
-
Donโt Rush:ย If the heat is too high, youโll end up with lemon-flavored scrambled eggs. Keep the water at a gentle simmer.
-
Use Fresh Lemons:ย Bottled juice lacks the complex oils found in fresh zest and juice, which are essential for that โbrightโ flavor.
-
Storage:ย Keep in an airtight jar in the fridge for up toย 2 weeks, or freeze for up toย 3 months.

Q&A
Q: Why is my lemon curd runny?
A:ย It likely wasnโt cooked long enough or hasnโt chilled completely. It needs to reach a certain temperature to allow the egg proteins to โset.โ If itโs still thin after 4 hours in the fridge, you can re-warm it over a double boiler with an extra egg yolk.
Q: Can I use the whole egg instead of just yolks?
A:ย Yes, you can use whole eggs, but the curd will be slightly lighter in color and have a less โcustardyโ mouthfeel. Yolks provide that deep gold color seen in your photo.
Q: Can I use lime or orange instead?
A:ย Absolutely! This ratio works perfectly for Lime Curd. For Orange or Grapefruit, you may want to reduce the sugar slightly as those fruits are naturally sweeter.
