Course: Condiment / Spread / Dessert Filling
Difficulty: Easy
Ingredients
- 1½ cups fresh lemon juice (about 8–10 lemons)
- 2 tablespoons finely grated lemon zest
- 2 cups granulated sugar
- 6 large eggs
- 2 large egg yolks
- 1 cup unsalted butter, cut into cubes
- ¼ teaspoon salt
- 1 teaspoon vanilla extract (optional)
Equipment
- Medium saucepan
- Whisk
- Fine mesh strainer
- Measuring cups
- Measuring spoons
- Citrus juicer
- Microplane or zester
- Heat-resistant spatula
- Sterilized mason jars with lids
Instructions
Step 1: Prepare the Lemons
Wash the lemons thoroughly under warm water. Dry them completely before zesting.
Using a fine zester, remove only the bright yellow peel, avoiding the bitter white pith.
Juice the lemons and strain the juice to remove seeds and excess pulp.
Step 2: Mix the Base
In a medium saucepan, whisk together:
- Eggs
- Egg yolks
- Sugar
- Salt
Continue whisking until the sugar begins dissolving.
Add:
- Fresh lemon juice
- Lemon zest
Mix until smooth.
Step 3: Cook the Lemon Curd
Place the saucepan over medium-low heat.
Cook while whisking constantly.
After about 8–12 minutes, the mixture will gradually thicken.
Do not allow it to boil rapidly, as the eggs can scramble.
The curd is ready when it coats the back of a spoon and reaches approximately 170°F (77°C).
Step 4: Add the Butter
Remove the saucepan from the heat.
Add the butter one piece at a time.
Whisk continuously until each cube melts completely before adding the next.
The butter creates the silky texture and glossy appearance that makes lemon curd irresistible.
If using vanilla extract, stir it in after all the butter has melted.
Step 5: Strain
Pour the lemon curd through a fine mesh strainer into a large measuring cup or bowl.
This removes:
- Lemon zest (if preferred)
- Tiny bits of cooked egg
- Any pulp
The result is an incredibly smooth and creamy curd.
Step 6: Fill the Jars
Pour the warm lemon curd into sterilized mason jars.
Leave about ¼ inch of headspace.
Seal the jars with clean lids.
Allow them to cool to room temperature.
Refrigerate for at least 2 hours before serving.

- Medium-low heat is the secret to a silky texture.

Frequently Asked Questions
