Easy Elderflower Cordial

When & where to pick elderflowers (UK)

Timing: late May–July, on a dry morning after dew has lifted. Avoid rainy days (dilutes pollen and flavour).
Best heads: freshly opened, creamy-white, fragrant; avoid brown or insect-damaged heads.
Where: clean hedgerows away from roads, sprayed fields, or dog-walk hotspots; or your own garden tree/shrub.
Wild picking etiquette: take a little from many plants; leave plenty for pollinators and later berries for wildlife.

Easy elderflower cordial recipe

This small-batch cordial makes about 1.5–2 litres — easy to scale up.

Ingredients

20–25 elderflower heads (shaken gently to dislodge insects; don’t wash if you can avoid it)
1.5 kg granulated sugar
1.2 litres water
2 unwaxed lemons (zest & juice)
1 unwaxed orange (optional, zest & juice)
25 g citric acid (optional but improves keeping quality)

Method

Make syrup: heat water and sugar in a large pan, stirring until dissolved. Bring just to the boil, then take off the heat.
Add flavour: add lemon zest, lemon juice, (orange if using), and citric acid. Stir.
Infuse: submerge elderflower heads (flowers down). Weigh with a plate so they’re under the syrup. Cover and leave 24 hours at cool room temp.
Strain: lift out the plate and flowers; pour through a sieve lined with muslin/coffee filters into a clean jug.
Bottle: funnel into sterilised bottles. Refrigerate. For longer storage, freeze in plastic bottles leaving headspace, or hot-bottle (see tips).

Clarity, flavour & storage tips

Don’t rinse blossoms: you’ll lose fragrant pollen — just shake gently outdoors.
Muslin matters: double-strain if you want bar-clear cordial.
Citric acid: extends fridge life and brightens flavour; most chemists/homebrew shops stock it.
Hot-bottling: warm clean bottles in a low oven (120 °C). Reheat strained cordial to ~80–85 °C, bottle and cap. Cool, then store cool & dark.
Freezing: simplest preservation — freeze in small bottles or ice-cube trays for cocktails and baking.
Shelf life: chilled: 3–4 weeks (with citric acid); frozen: 6–12 months; hot-bottled: several months if unopened.

Serving ideas & variations

Classic: dilute 1:6 with chilled still or sparkling water; add lemon slices and mint.
Rhubarb twist: simmer 300 g chopped rhubarb in the syrup for 5 minutes before adding flowers (strain well).
Cucumber cooler: add cucumber ribbons and a few crushed juniper berries to the jug.
Cocktails: 25 ml cordial + 35 ml gin + top with soda; or a dash in prosecco.
Desserts: drizzle over fruit salad, stir into whipped cream, or make elderflower jelly with seasonal berries.

How to grow elder (Sambucus) for a yearly harvest

Growing your own elder makes cordial production effortless — you’ll have clean blossoms at arm’s reach and birds to enjoy the autumn berries.

What to plant

Native elder (Sambucus nigra): vigorous, reliable flower/berry production; prune to keep tidy.
Ornamental elders: S. nigra ‘Black Lace’ (dark lacy foliage, pinkish flowers), ‘Sutherland Gold’ (chartreuse). Both still usable for cordial.

Position & care

Aspect: sun or light shade; flowers best in full sun.
Soil: tolerates most soils; avoid waterlogged sites.
Size control: prune in late winter; stool to a framework if you want a shrub rather than a small tree.
Containers: possible with dwarf/ornamental forms in large planters; feed and water regularly.

FAQs

Are elderflowers safe to eat?

Yes, when prepared as cordial/syrup. Avoid stems and leaves (they contain compounds that are removed by straining/heating). Always identify plants confidently before foraging.

Can I use dried elderflowers?

You can, but fresh gives the brightest flavour. Dried flowers vary in strength — start with half the weight and adjust to taste.

My cordial turned cloudy — did I ruin it?

Not ruined; it’s likely fine sediment or pectin. Double-strain and chill. Cloudiness doesn’t affect flavour.
