Instructions for making this Lemon Curd Tart
Follow along, frame by frame, as we turn simple ingredients into a glassy-smooth lemon curd. We start with everything —eggs, caster sugar, fresh lemon juice and zest, —then whisk to combine, warm gently over a bain-marie, and watch the mixture thicken to nappe (about 82°C). Off the heat we dissolve in the butter then the gelatin, emulsifying for shine, strain for silkiness, and the curd is ready to pour and chill.
STEP 1
Make the pastry and block up ready to rest
STEP 2
Zest and juice the lemons
STEP 3
Add in the sugar and eggs
STEP 4
Cook over the stove until it thickens. Take off the heat and add butter and once incorporated add in the softened gelatine sheets.
Pro Tips for this Lemon Tart
- Texture control: Blend in butter off the heat to create a velvety emulsion
- Precision: Use a thermometer—79°C is the perfect temperature for curd.
- Gloss factor: Gelatine gives professional sheen and prevents water separation.
- Make ahead: Bake pastry shells and prepare curd a day in advance.
Kitchen Tests: Foolproof Pastry & Curd for this Lemon Curd Tart
Lemon Curd Checks
- Nappe Test: Coat the back of a spoon and draw a line with your finger; if it stays clear, the curd is ready.
- Thermometer Check: Target 79°C—thick enough without scrambling eggs.
- Bubble Edge: Tiny steam bubbles at the edge signal it’s cooked; stop before boiling.
- Sieve Smoothness: Strain through a fine sieve. Minimal cooked specks = perfect technique.
Sweet Short Pastry Checks
- Pinch Test: Dough holds together without cracking but isn’t sticky.
- Rested Dough: Cool, firm, and easy to roll. Too soft? Chill longer. Too hard? Warm briefly.
- Rolling Flexibility: Dough should lift without breaking or tearing.
- Blind Bake: Shell should look pale golden and dry before filling.
Substitutions for this Lemon Curd Tart
Butter (in pastry and curd)
Dairy-free margarine or vegan butter
Choose a block-style vegan butter for similar structure in pastry. In curd, add a pinch of salt for flavour balance.
Gluten-Free Substitutions
| Ingredient | Swap | Notes |
|---|---|---|
| Plain Flour (in pastry) | Gluten-free all-purpose flour blend | Choose one with xanthan gum or add ½ teaspoon per 250 g flour for elasticity. |
| Dusting flour for rolling | Cornflour or rice flour | Prevents sticking without adding gluten. |
Variations for this Lemon Curd Tart
Gluten-free pastry: Roll between sheets of baking paper for less cracking.
Dairy-free pastry: Chill dough well, as dairy-free fats melt faster.

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.
FAQs For this Lemon Curd Tart
Why did my lemon curd curdle or scramble?
The heat was too high or the mixture cooked too quickly. Always use a bain-marie (water bath) and cook low and slow, stopping at 79°C for a silky curd.
How do I stop my tart pastry from shrinking?
Rest the dough in the fridge for at least 30 minutes before baking and avoid stretching it when lining the tin. Blind baking with pie weights also helps
How do I make my lemon tart extra glossy?
Whisk in butter off the heat for shine, and brush with a thin layer of apricot nappage or neutral glaze once set.
