Step-by-Step Guide to Making Mary Berry Lemon Curd
Step 1: Prepare the lemons
Zest the lemons finely and squeeze out the juice, removing any seeds. The zest adds aroma, and the juice brings the bright flavour.
Step 2: Combine the ingredients
Place the lemon zest, lemon juice, sugar, and cubed butter into a heatproof bowl set over a saucepan of simmering water.
Step 3: Melt the mixture
Stir gently until the butter melts completely and the sugar dissolves, giving you a smooth base.
Step 4: Add the eggs
Whisk the eggs and optional yolk in a separate bowl, then slowly pour them into the warm lemon mixture while whisking continuously to prevent scrambling.
Step 5: Thicken the curd
Cook gently for 8–10 minutes, stirring constantly until the curd thickens enough to coat the back of a spoon.
Step 6: Strain for smoothness
Pour the curd through a fine sieve to remove the zest and create a perfectly silky finish.
Step 7: Jar and cool
Transfer to a clean glass jar and allow it to cool completely before refrigerating.

What I Got Wrong (And How I Fixed It)
- Curds formed in the eggs — whisking continuously solved it
- Curd too runny — cooking a few minutes longer fixed the texture
- Flavour too mild — adding more zest boosted brightness
- Too sweet — using larger, more acidic lemons balanced it
Healthier Version of Mary Berry Lemon Curd

FAQs
Why does my lemon curd curdle while cooking?
Lemon curd curdles when the heat is too high or the eggs are added too quickly. Keeping the bowl over gentle simmering water and whisking continuously prevents the eggs from scrambling and keeps the curd silky smooth.
How do I know when lemon curd is fully thickened?
Lemon curd is ready when it coats the back of a spoon and leaves a clean line when you run your finger through it. It continues to thicken as it cools, so remove it from the heat once it reaches this stage.
Why is my lemon curd too runny even after cooling?
A runny curd usually means it wasn’t cooked long enough. Returning it to gentle heat and stirring for a few more minutes helps it reach the right consistency without overcooking.
How can I make my lemon curd more lemony?
Using extra lemon zest or squeezing an additional half lemon creates a brighter lemon flavour. Fresh lemons always work better than bottled juice for a stronger citrus taste.
What does Mary Berry lemon curd taste like?
Mary Berry lemon curd has a bright, tangy lemon flavor balanced with buttery richness. It’s smooth, creamy, and not overly sweet, making it perfect for spreading, filling desserts, or layering in cakes.
Where did lemon curd originally come from?
Lemon curd was first created in England during the early 19th century. It began as a luxury spread served with tea-time scones and cakes, eventually becoming a classic part of British home baking.
