Ingredients
Method
- Sterilise jars in a 140°C oven for 15 minutes.
- Place lemon zest, lemon juice, caster sugar, cold cubed butter, and beaten eggs and yolks in a large heatproof bowl. Do not mix yet.
- Place bowl over a pan of gently simmering water — base must not touch the water. Stir everything together. Cook over simmering water for 10–15 minutes, stirring constantly, until the curd coats the back of a spoon thickly and a drawn line holds its shape. Never let it boil.
- Remove from heat. Strain through a fine sieve into a clean jug.
- Pour immediately into warm sterilised jars. Place a disc of baking parchment on the surface. Seal. Label. Cool then refrigerate.
Notes
Use unwaxed lemons — the wax can affect the flavour.
Include the extra egg yolks — they give a richer colour and more stable set.
Never let the curd boil — keep the water at a gentle simmer throughout.
Stir constantly — do not leave it unattended.
Always strain before potting for a completely smooth curd.
The curd thickens further as it cools — it will look slightly runny when hot.
Stores in the fridge for up to 4 weeks. Freezes for up to 3 months.
