This Mary Berry elderflower cordial is a luminously pale, floral syrup with a clean citrus brightness and a delicate honeyed finish. Made with fresh elderflower heads, unwaxed lemons, and a straightforward sugar base, it produces a cordial that is both fragrant and refreshingly clear, with none of the artificial sweetness of shop-bought versions.

The recipe suits complete beginners and requires no specialist equipment beyond a large pan, a piece of muslin, and a handful of sterilised bottles. It scales easily for larger batches, keeps well throughout summer, and works just as beautifully poured over ice as it does stirred into sparkling wine or baked into sponges. From start to finish, including steeping time, it is ready in around 25 hours.

How to Make Mary Berry Elderflower Cordial

Prepare the elderflowers:

Check the elderflower heads carefully and shake off any insects. Do not wash them, as rinsing removes the pollen that gives the cordial its distinctive musky floral fragrance. Trim the thicker stalks away, keeping just the small white flower clusters.

Make the sugar syrup:

Pour 750ml of boiling water into a large, clean heatproof bowl or saucepan and add the caster sugar. Stir steadily until the sugar has dissolved completely and the liquid is clear rather than cloudy, this ensures a smooth cordial without any gritty residue.

Add the flavourings:

While the syrup is still hot, add the pared lemon zest, orange zest, lemon juice, and citric acid. Stir well to combine. The citric acid acts as a natural preservative and sharpens the flavour, preventing the cordial from tasting overly sweet.

Steep the elderflowers:

Submerge the elderflower heads fully into the warm syrup. Press them down gently with a wooden spoon so all the blossoms are covered. Cover the bowl with a clean tea towel or cling film and leave to steep at room temperature for 24 hours, giving the flowers time to infuse deeply into the syrup.

Strain the cordial:

Line a large colander or sieve with a double layer of clean muslin or a new, clean J-cloth and set it over a large jug or saucepan. Pour the steeped mixture through slowly, allowing the liquid to drain naturally without pressing the flowers, which keeps the cordial clear and prevents any bitter notes.

Sterilise the bottles:

Wash glass bottles in hot soapy water, rinse thoroughly, then place upright on a baking tray and heat in the oven at 140C (120C fan) for 15 minutes. Allow them to cool slightly before filling. Sterilising removes bacteria that can cause early spoilage.

Bottle and seal:

Using a funnel, pour the strained cordial into the warm sterilised bottles. Seal with sterilised lids or stoppers immediately while the bottles are still warm. Label each bottle with the date. The cordial is ready to use straight away or store.

Serve:

Dilute approximately one part cordial to eight parts cold sparkling or still water. Taste and adjust the ratio to preference. Serve over ice with a slice of lemon or a sprig of fresh mint for a clean, pale golden drink with a floral elderflower aroma.

Tips for the Best Elderflower Cordial

01 Why does my elderflower cordial look cloudy instead of clear?

+−

Cloudiness usually means the flowers were pressed or squeezed during straining. Always let the liquid drain through the muslin naturally under gravity, and avoid pressing or squeezing the flowers or cloth. A second pass through fresh muslin will often clear a slightly hazy cordial.

02 Why does my cordial taste bland or weakly flavoured?

+−

The elderflowers may not have been ripe enough or the heads may have been too small. Pick flowers when they are fully open, creamy white in colour, and at their most fragrant, typically on a warm dry day. Avoid any heads that have already started to turn brown, as the flavour will be musty rather than floral.

03 Why has my cordial started fermenting in the bottle?

+−

Fermentation in the bottle indicates either insufficient citric acid or bottles that were not properly sterilised before filling. Always measure the citric acid accurately and ensure bottles are fully sterilised. Once opened, transfer cordial to the fridge and use within four to six weeks.

04 Why does my cordial taste bitter at the edges?

+−

Bitterness usually comes from including too much of the thick green stalk. Trim back the flower heads so only the small flower clusters and very fine stems remain. The large woody stems contain compounds that leach a noticeably bitter quality into the syrup during the long steep.

05 How do I know when my elderflowers are at their best for picking?

+−

The flowers should be fully open, bright creamy white, and strongly fragrant when held close to the nose. Pick in the morning of a dry, sunny day when the pollen is most concentrated. Avoid any heads where the tiny florets are dropping or where the colour is fading to yellow, as the flavour will already be past its peak.

FAQs

Can I use dried elderflowers instead of fresh ones?

+−

Dried elderflowers can be used, though the resulting cordial will have a noticeably less vibrant and slightly more earthy flavour than one made with fresh heads. If using dried flowers, reduce the quantity to around 15g and steep for the same 24 hours. The colour will be a deeper gold rather than the pale champagne you get with fresh flowers.

Can I make this elderflower cordial recipe without citric acid?

+−

Citric acid is strongly recommended as it preserves the cordial and brightens the flavour. However, if it is unavailable, you can increase the quantity of lemon juice by two tablespoons per lemon used. Be aware that a cordial made without citric acid will have a shorter shelf life of around two weeks in the fridge and is more prone to early fermentation.

Can I use this cordial as an ingredient in baking?

+−

Absolutely, the cordial works very well as a baking ingredient. Use it to soak a sponge layer before assembling a cake, stir it into buttercream in place of milk for a floral finish, or add a few tablespoons to whipped cream for a delicate summer dessert. When baking with it, keep in mind the cordial is already sweetened, so reduce any additional sugar in the recipe slightly to balance the flavour.

Can I double this elderflower cordial recipe for a larger batch?

+−

The recipe doubles very straightforwardly. Simply scale all quantities proportionally and use a larger bowl for steeping. You will need more sterilised bottles on hand for bottling. The steeping time remains 24 hours regardless of batch size, as this is about infusion depth rather than quantity.

Is this elderflower cordial suitable for children?

+−

Yes, this is a non-alcoholic cordial and is entirely suitable for children when diluted with still or sparkling water in the usual way. The citric acid is a food-safe preservative used widely in commercially produced drinks and poses no concern for children when the cordial is consumed diluted at the recommended ratio.
