Mary Berry Lemon Curd Recipe

This Mary Berry lemon curd is the kind of homemade staple that instantly makes toast, scones, and sponge cakes feel special. It’s silky, glossy, and thick enough to hold its shape, with a bright lemon tang balanced by buttery richness. The method is simple and beginner-friendly as long as you cook it gently and keep stirring. Total time is about 30 minutes, plus cooling time for it to fully set.

Ingredients

For the lemon curd

4 unwaxed lemons (finely zest all 4, then juice them, about 150ml juice)
200g caster sugar
3 large eggs
1 large egg yolk
100g unsalted butter, cut into small cubes
Pinch of fine salt (optional, but lovely for balance)

To store (recommended)

2 small sterilised jars with lids (about 300ml each)

How to Make Mary Berry Lemon Curd Recipe

Prepare the oven: Lemon curd is made on the hob, not baked, but the oven is handy for sterilising jars. If you’re oven-sterilising, preheat to 140°C (120°C fan) and place clean jars (not the rubber seals) on a tray for 15 minutes.
Sterilise the jars and lids: If you prefer, sterilise jars in the dishwasher on a hot cycle, or in a pan of simmering water for 10 minutes. Keep everything warm and ready so the curd goes into hot jars.
Set up a gentle bain-marie: Fill a saucepan with a few centimetres of water and bring it to a very gentle simmer. Sit a heatproof bowl on top, making sure the bottom of the bowl does not touch the water.
Mix the base: In the bowl, whisk together the caster sugar, whole eggs, egg yolk, lemon zest, lemon juice, and a pinch of salt until smooth. This is your “mixing” stage, get it well combined before heat is involved.
Cook slowly (the “baking” stage, but on the hob): Place the bowl over the simmering water and stir constantly with a silicone spatula or wooden spoon, making sure you scrape the sides and bottom. Cook for 10 to 15 minutes until the curd thickens enough to coat the back of the spoon.
Check the set: Run a finger through the curd on the back of the spoon. If it leaves a clear line that holds its shape, it’s ready. If you have a thermometer, aim for about 75°C to 80°C for a safe, thick curd without scrambling.
Finish with butter: Take the bowl off the heat and whisk in the butter cubes a few at a time until fully melted. The curd should look glossy and a little lighter in colour.
Strain (optional, but worth it): For an extra-silky texture, strain through a fine sieve into a jug. This catches any bits of zest you do not want, and any tiny eggy flecks.
Assemble and jar: Pour the warm curd into sterilised jars, leaving a small gap at the top. Seal with lids.
Cool and set: Let the jars cool to room temperature, then refrigerate for at least 4 hours (overnight is even better) so the lemon curd thickens properly.

Tips for Perfect Lemon Curd

Why is my lemon curd runny?

It simply needs a little longer over gentle heat. Keep stirring and cook until it coats the back of a spoon. Lemon curd also thickens as it chills, so judge the final texture after it has had time in the fridge.

How do I stop lemon curd from tasting eggy?

Low heat is everything. If the heat is too high, the eggs start to cook too quickly and the flavour can turn “eggy.” Use a bain-marie, keep the water barely simmering, and stir constantly.

What if my lemon curd has little lumps?

That’s usually tiny bits of cooked egg from overheating or not stirring into the corners of the bowl. Strain the curd through a fine sieve while it’s warm and it will be perfectly smooth.

How do I get a brighter lemon flavour?

Use unwaxed lemons and do not skip the zest. The zest gives that fragrant, fresh lemon hit that juice alone cannot deliver.

Serving Suggestions

Spread thickly on toast, crumpets, or warm English muffins

Storage

Room Temperature

Let the jars cool at room temperature after filling, then refrigerate. For food safety, do not leave lemon curd out for extended periods.

Refrigerator

Store in sealed sterilised jars in the fridge for up to 2 weeks. Always use a clean spoon to keep it fresh, and keep the lid on between uses.

Freezing

Lemon curd freezes well for up to 3 months. Freeze in freezer-safe containers with a little headspace. Thaw overnight in the refrigerator and stir well before using.

FAQs

How long does homemade lemon curd take to set?

It thickens a little as it cools, but for the best set, refrigerate it for at least 4 hours. Overnight chilling gives the thickest, spreadable texture.

Can I use bottled lemon juice instead of fresh lemons?

Fresh lemon juice tastes noticeably brighter, and the zest adds most of the fragrance, so fresh is strongly recommended. If you must use bottled juice, choose 100% lemon juice (not from concentrate if possible) and consider adding a little extra zest from a fresh lemon.

Why did my lemon curd split or look greasy?

This can happen if the curd gets too hot or if the butter is added while the mixture is still aggressively heating. Remove from heat before adding the butter and whisk it in gradually. If it splits, whisk vigorously and strain; it often comes back together as it cools.

Can I make lemon curd without a bain-marie?

You can cook it directly in a saucepan over very low heat, but it’s easier to overheat and scramble the eggs. A bain-marie gives gentler, more even heat and is the safest method for beginners.

Can I water-bath can lemon curd for pantry storage?

Home canning lemon curd requires specific tested methods for safety. This recipe is intended for refrigerator storage (or freezing). If you want shelf-stable lemon curd, use an approved canning recipe from a trusted authority and follow it exactly.
