Homemade Lemon Curd: Velvety Smooth Filling Recipe
Introduction
Homemade lemon curd is a luscious, velvety smooth filling perfect for tarts, cakes, or simply enjoyed on toast. This easy recipe highlights fresh lemon juice and zest, delivering a bright and tangy flavor that’s hard to resist.

Ingredients
- 4 large egg yolks
- 2 large whole eggs
- 3/4 cup (150g) granulated sugar
- 1/2 cup (120ml) freshly squeezed lemon juice
- 2 tablespoons lemon zest
- 1/2 cup (113g) unsalted butter, cold and cubed
Instructions
- Step 1: In a medium heatproof bowl, whisk together the egg yolks, whole eggs, and granulated sugar until smooth and pale.
- Step 2: Add the lemon juice and lemon zest to the egg mixture and whisk until combined.
- Step 3: Place the bowl over a pot of gently simmering water (double boiler), making sure the bowl does not touch the water.
- Step 4: Cook the mixture, stirring constantly with a heat-resistant spatula or whisk, until it thickens enough to coat the back of a spoon. This should take about 10-15 minutes.
- Step 5: Remove the bowl from heat and immediately whisk in the cold cubed butter, a few pieces at a time, until fully incorporated and smooth.
- Step 6: Strain the curd through a fine mesh sieve into a clean container to remove any cooked egg bits for an extra smooth texture.
- Step 7: Allow the lemon curd to cool to room temperature, then cover and refrigerate. It will thicken further as it chills.
Tips & Variations
- Use both lemon juice and zest for the most vibrant, fresh flavor.
- For a dairy-free version, substitute butter with coconut oil, but the texture may be slightly different.
- If the curd seems curdled, whisk vigorously off the heat to bring it back together.
- Add a splash of vanilla extract for a subtle twist.
Storage
Store lemon curd in an airtight container in the refrigerator for up to 1 week. To use, bring it to room temperature or warm gently over a double boiler if you want a more spreadable consistency.

FAQs
Can I use bottled lemon juice instead of fresh?
Freshly squeezed lemon juice is best for flavor and brightness, but in a pinch, bottled lemon juice can be used. Avoid any that contain added preservatives or sweeteners.
How can I tell when the lemon curd is done cooking?
The curd is ready when it thickens enough to coat the back of a spoon and leaves a clear line when you run your finger through it. It should not be runny but not too thick yet, as it will thicken more when chilled.

Ingredients
Egg Mixture
- 4 large egg yolks
- 2 large whole eggs
Main Ingredients
- 3/4 cup (150g) granulated sugar
- 1/2 cup (120ml) freshly squeezed lemon juice
- 2 tablespoons lemon zest
- 1/2 cup (113g) unsalted butter, cold and cubed
Instructions

- Cook the Mixture: Place the bowl over a pot of gently simmering water (double boiler method). Stir continuously with a wooden spoon or heatproof spatula, making sure to scrape the sides and bottom to prevent curdling or sticking.
- Add Butter: As the mixture thickens to a custard-like consistency (about 10-15 minutes), remove it from heat and immediately add the cold cubed butter, stirring until completely melted and the curd is smooth and glossy.
- Strain and Cool: Pour the lemon curd through a fine mesh sieve into a clean jar or container to remove any cooked egg bits for an ultra smooth texture. Let it cool to room temperature, then refrigerate.
- Chill: Cover the curd with plastic wrap pressed directly on the surface to prevent a skin from forming. Refrigerate for at least 2 hours to let it fully set and thicken before using.
