The hedgerow's summer gift

There is a moment in late May or early June when the British countryside is suddenly frothy with elderflowers. The creamy, flat-topped heads appear along hedgerows, woodland edges and forgotten corners, filling the air with a sweet, musky scent that signals summer is truly on its way. For anyone who loves wild food and rural ways, making elderflower cordial is one of the most rewarding traditions of the year. It costs very little, takes only a morning to gather and a day to infuse, and rewards you with a fragrant, golden syrup that tastes like bottled sunshine. The key is to pick on a dry, sunny morning and to turn the blossoms into cordial while they are still fresh and full of perfume.

Picking with care and respect

Elder (Sambucus nigra) is a generous tree, but it deserves careful handling. Choose a dry morning after the dew has lifted, ideally between late May and mid-June when the flowers are at their peak. Avoid picking after rain, as wet blossoms lose much of their fragrance and can turn mouldy quickly. Look for heads that are fully open, creamy white and heavy with pollen. Leave behind any with brown flowers, green berries forming, or a sour smell. It is also wise to avoid busy roadsides, sprayed verges and fields where livestock have recently been. Take only what you need — a good basketful of about 20 to 25 heads is plenty for a large batch — and always leave several heads on each tree so that birds and insects can enjoy the berries later in the year. Snip the stalks with scissors rather than pulling, and carry your haul in a shallow basket or paper bag to prevent crushing.

Preparing your haul

Once home, spread the elderflowers on a clean cloth or tray in a cool room. Do not wash them unless absolutely necessary; a gentle shake is usually enough to dislodge insects, tiny beetles and bits of leaf. If you must rinse them, do so briefly in cold water and pat dry with a clean tea towel. You will need a large saucepan or preserving pan, a wooden spoon, a fine sieve, a muslin square or jelly bag, and sterilised bottles. For the cordial itself, gather 1.5kg of caster sugar, 1.5 litres of water, two unwaxed lemons, and 30g of citric acid. Citric acid is not strictly essential, but it acts as a preservative and gives the cordial a lovely tart edge. It is sold in chemists and brewing shops, and it keeps your cordial fresh for weeks rather than days.

The cordial recipe

Begin by pouring the water into your pan and bringing it to the boil. Add the caster sugar and stir over a low heat until it has completely dissolved. Remove from the heat and allow the syrup to cool to room temperature. This step matters: pouring hot syrup over the flowers cooks them and dulls that delicate perfume. While the syrup cools, zest the lemons in wide strips, avoiding the bitter white pith, then halve and juice them. Shake your elderflowers once more, then add them to the cooled syrup along with the lemon zest, lemon juice and citric acid. Stir gently, cover the pan with a clean cloth or lid, and leave it in a cool place for 24 to 48 hours. Stir once or twice a day. The liquid will turn a pale gold and smell intensely floral. After infusing, strain the cordial through a muslin-lined sieve into a clean jug or bowl, then funnel it into sterilised bottles. Seal and store in the fridge, where it will keep for up to six weeks. For longer storage, pour into plastic bottles, leaving a little headroom, and freeze.

Straining, bottling and variations

Sterilise your bottles by washing them in hot soapy water, rinsing well, and drying them in a low oven for ten minutes. Let them cool before filling. If you prefer a clearer cordial, strain it twice through fresh muslin. You can also experiment with flavour. A sprig of mint, a few strips of orange zest, or a teaspoon of rosewater added with the lemons can be lovely. Some foragers add a handful of gooseberries or a chopped apple to the infusion for extra depth, though this changes the colour. If you omit the citric acid, reduce the infusion time to 24 hours and use the cordial within a week, keeping it refrigerated at all times. Always label your bottles with the date so you know how long they have been stored.

Ways to enjoy your cordial

Elderflower cordial is wonderfully versatile. Dilute it with still or sparkling water — roughly one part cordial to five parts water — and serve over ice with a slice of lemon and a sprig of mint. It makes a beautiful partner for gin, vodka or prosecco, and it can be drizzled over fruit salads, yoghurt, panna cotta or a gooseberry fool. Try freezing it in ice cube trays and dropping a few into a glass of cold white wine or lemonade. It also makes a refreshing sorbet or a delicate poaching liquor for peaches and pears. However you serve it, a bottle of homemade elderflower cordial captures a fleeting moment of the British summer — a true taste of the hedgerow to enjoy long after the blossoms have gone.
