Instructions for making this Lemon Curd Tart
Follow along, frame by frame, as we turn simple ingredients into a glassy-smooth lemon curd. To begin, the eggs, caster sugar, fresh lemon juice, and lemon zest are combined in a bowl, then whisked together until smooth and evenly blended. Next, the bowl is placed over a gentle bain-marie, allowing the mixture to warm slowly and evenly without scrambling the eggs.
As the curd heats, it gradually thickens and becomes glossy. Meanwhile, continuous stirring helps control the temperature and encourages a silky texture. Once the mixture reaches nappe stage, at about 82°C, it should lightly coat the back of a spoon.
Then, off the heat, the butter is added and dissolved into the warm curd, creating richness, shine, and a smooth emulsion. After that, the softened gelatin is added and mixed through until fully dissolved. Finally, the curd is strained to remove zest and any small particles, ensuring a silky finish. Once poured into the tart shell and chilled, it sets into a bright, glossy lemon filling.
STEP 1
To begin, prepare the pastry by combining the ingredients and mixing until a smooth, even dough is formed. As the mixture comes together, take care not to overwork the dough, as excessive mixing can develop too much gluten and result in a tougher pastry. Once fully combined, the dough is gently gathered together and shaped into a neat block.
Next, the pastry is lightly flattened into an even rectangle, making it easier to roll after chilling. Meanwhile, shaping the dough before resting helps it cool more evenly and reduces the amount of handling required later. Afterward, the dough is wrapped well to prevent it from drying out and placed in the refrigerator to rest.
Importantly, this resting period allows the flour to fully hydrate while also giving the gluten time to relax. As a result, the pastry becomes easier to roll, less likely to shrink during baking, and more tender in the finished tart. Ultimately, taking the time to properly block and rest the pastry provides the foundation for a crisp, delicate, and evenly baked tart shell.
STEP 2
To begin, thoroughly wash and dry the lemons to remove any surface impurities. Next, using a fine zester or microplane, carefully remove the outer yellow zest, taking care to avoid the bitter white pith beneath. Meanwhile, zesting the lemons before juicing makes the process easier and helps maximise the amount of flavour collected.
Once the zest has been prepared, cut the lemons in half and juice them thoroughly, extracting as much juice as possible. Additionally, straining the juice helps remove any seeds and excess pulp, resulting in a smoother finished curd. As the zest and juice are combined later in the recipe, they work together to provide both the bright citrus aroma and the fresh tangy flavour that give lemon curd its distinctive character. Ultimately, this preparation step lays the foundation for a vibrant, well-balanced filling.
STEP 3
Next, add the eggs and sugar to a mixing bowl. Then, whisk the ingredients together thoroughly until they are well combined and the sugar has begun to dissolve. As you continue whisking, the mixture will become smoother and slightly lighter in appearance.
Meanwhile, ensuring the eggs and sugar are evenly blended helps create a consistent base for the lemon curd. Additionally, proper mixing allows the sugar to disperse throughout the eggs, promoting even thickening during cooking. Once fully combined, the mixture is ready for the addition of the lemon juice and zest before proceeding to the next stage of the recipe.
STEP 4
Next, place the mixture over the stove or a gentle bain-marie and cook slowly while stirring continuously. As the temperature gradually increases, the eggs begin to thicken the mixture, transforming it from a thin liquid into a smooth, creamy curd. Meanwhile, constant stirring helps prevent the eggs from overcooking and ensures an even, silky texture throughout. Continue cooking until the curd reaches the desired consistency and thickly coats the back of a spoon.
Once the curd has thickened, immediately remove it from the heat to prevent further cooking. Then, gradually add the butter, stirring continuously until it has completely melted and is fully incorporated. As the butter emulsifies into the curd, it contributes richness, shine, and a smoother mouthfeel. Afterward, add the softened gelatine sheets and stir well until they have completely dissolved. Finally, the gelatine helps stabilise the curd, providing a clean slice and a beautifully smooth set once chilled.

Storage Conditions for Lemon Curd Tart
To maintain the best flavour, texture, and food safety, the Lemon Curd Tart should be stored under refrigeration as soon as it has fully set. Once chilled, cover the tart loosely with plastic wrap or place it in an airtight container to protect it from absorbing odours and to prevent the pastry from drying out.
Furthermore, storing the tart at 4°C or below helps preserve the freshness of both the lemon curd filling and the pastry shell. While the tart will remain safe to eat for several days, it is generally at its best within the first 2–3 days, when the pastry remains crisp and the filling retains its smooth, glossy texture.
If preparing ahead, the pastry shell can be baked and stored separately in an airtight container at room temperature for up to 2 days before filling. Meanwhile, the lemon curd can be prepared in advance and refrigerated for up to 5 days, allowing the tart to be assembled closer to serving time for optimal quality.
Additionally, avoid storing the tart in direct sunlight or at room temperature for extended periods, as the egg-based filling can soften and food safety may be compromised. Before serving, remove the tart from the refrigerator for approximately 10–15 minutes to allow the flavours to develop fully and the filling to soften slightly.
Storage Summary
- Refrigerated: 4°C or below
- Best quality: 2–3 days
- Maximum storage: Up to 5 days refrigerated
- Freezing: Not generally recommended, as the curd may weep and the pastry can lose its crisp texture upon thawing
- Serving: Allow 10–15 minutes at room temperature before serving for the best flavour and texture.
Mini Tips for the Perfect Lemon Curd Tart
- Zest First, Juice Second:
Always zest your lemons before juicing—it’s easier and you capture maximum oils for flavour. - Strain for Silkiness:
Pass the curd through a fine sieve to remove zest and any cooked egg bits, leaving it ultra-smooth. - Chill Your Pastry Dough:
Cold, rested pastry is easier to roll, less likely to shrink, and gives you a crisp shell. - Shine Like a Pâtisserie:
Brush the top with a thin layer of warmed apricot nappage for a glassy, bakery-style finish. - Serve Chilled but Not Ice-Cold:
Let the tart sit at room temp for 5–10 minutes before slicing to enhance flavour and texture.
