Bursting with a refreshing citrus flavor, it's a perfect balance of sweet and tangy. Whether you’re a seasoned cook or a beginner in the kitchen, this guide will walk you through making the perfect lemon curd. Read on to discover the essential ingredients, step-by-step instructions, and tips for serving and presenting this delectable treat.

What is Lemon Curd?
Lemon curd is a smooth, velvety spread made from lemons, sugar, butter, and eggs. It has a rich, creamy texture and a vibrant lemon flavor, making it a popular choice for spreading on scones, filling pastries, or layering in cakes. Unlike other preserves, lemon curd is thickened with eggs rather than pectin, giving it a unique custard-like consistency.
Ingredients List for Lemon Curd
To make the best lemon curd, you'll need the following ingredients:
- 3 large eggs: Eggs are the key thickening agent in lemon curd, providing the rich, custardy texture.
- 1 ¼ cups granulated sugar: Sugar balances the tartness of the lemons and adds sweetness.
- ½ teaspoon kosher salt: Salt enhances the flavors and balances the sweetness.
- ⅔ cup lemon juice (3 to 4 medium lemons): Freshly squeezed lemon juice gives the curd its bright, zesty flavor.
- ½ cup butter, cut into slices at room temperature: Butter adds creaminess and richness to the curd.
- 1 tablespoon lemon zest: Lemon zest intensifies the citrus flavor and adds a fragrant aroma.
Substitutions and Variations
If you’re looking to switch things up, consider these substitutions and variations:
- Lime Curd: Substitute lime juice and zest for lemon for a tangy twist.
- Orange Curd: Use orange juice and zest for a sweeter, milder flavor.
- Vegan Lemon Curd: Replace eggs with cornstarch or agar-agar and use dairy-free butter.
- Herb-Infused Curd: Add a sprig of rosemary or thyme while cooking for a subtle herbaceous note.
Step-by-Step Cooking Instructions
Creating lemon curd at home is a straightforward process. Follow these steps to ensure your lemon curd turns out perfectly every time:

- Prepare Your Ingredients: Measure out all your ingredients before you begin. Juice and zest the lemons, and cut the butter into slices.
- Whisk Eggs and Sugar: In a medium saucepan, whisk together the eggs, sugar, and salt until well combined.
- Add Lemon Juice and Zest: Stir in the lemon juice and zest. The mixture will be quite liquidy at this stage.
- Cook Over Medium Heat: Place the saucepan over medium heat. Cook, stirring constantly, until the mixture thickens and coats the back of a spoon. This should take about 8-10 minutes.
- Add Butter: Remove the saucepan from heat and immediately stir in the butter, one piece at a time, until fully melted and incorporated.
- Strain the Curd: For a silky-smooth texture, strain the lemon curd through a fine-mesh sieve into a bowl.
- Cool and Store: Let the curd cool to room temperature, then transfer it to a jar or airtight container. Refrigerate until fully chilled.
How to Cook Lemon Curd: A Step-by-Step Guide
Step 1: Gather and Prepare Ingredients
Begin by juicing and zesting your lemons. This preparation step is crucial to ensure everything is ready to go once you start cooking.
Step 2: Whisk Together Eggs, Sugar, and Salt
In a heavy-bottomed saucepan, combine the eggs, sugar, and salt. Whisk until the mixture is smooth and the sugar begins to dissolve.
Step 3: Incorporate Lemon Juice and Zest
Add the freshly squeezed lemon juice and the finely grated lemon zest to the egg mixture. Whisk thoroughly to combine.
Step 4: Heat the Mixture
Place the saucepan over medium heat. Stir constantly with a wooden spoon or heatproof spatula to prevent the eggs from curdling.
Step 5: Monitor the Consistency
As the mixture heats, it will begin to thicken. Continue stirring until it reaches a custard-like consistency and coats the back of a spoon.
Step 6: Add Butter Gradually
Remove the saucepan from the heat. Add the butter slices one at a time, stirring after each addition until the butter is completely melted and the curd is smooth.
Step 7: Strain for Smoothness
Pour the lemon curd through a fine-mesh sieve into a clean bowl to remove any bits of cooked egg or zest.
Step 8: Cool and Store
Allow the lemon curd to cool slightly before transferring it to a jar. Refrigerate for at least 2 hours or until fully set.
Common Mistakes to Avoid
- Overcooking: Cooking the curd on too high heat or for too long can cause it to curdle.
- Not Stirring Constantly: Failing to stir continuously can result in uneven thickening and lumps.
- Skipping the Strain: Not straining the curd can leave it with a gritty texture from the zest or cooked egg bits.
- Using Bottled Lemon Juice: Freshly squeezed lemon juice is essential for the best flavor.
