Homemade Elderflower Syrup

Elderflower syrup gets the best fragrance when you harvest the flower heads on a dry, sunny morning, when they are in full bloom and have an intense, honey-like scent. Look for creamy white clusters with no brown or wilting petals. Do not rinse the flowers, as water would wash away the essential oils. Simply inspect each head carefully and gently shake out any insects or small beetles.

Using scissors or a small knife, trim away the thick green stems as close to the flower clusters as possible. Tannic compounds in the stems can make the finished drink unpleasantly bitter, so take a moment to remove them thoroughly.

Thoroughly scrub the lemons in hot water to remove any wax coating, then dry and slice thinly with the peel still on. Remove any seeds you come across, as they can add a bitter note to the finished drink. Organic lemons work best here since the peel goes directly into the infusion.

In a large pot or wide-mouthed preserving jar, alternate layers of elderflower blossoms and lemon slices. Sprinkle with citric acid, roughly 20 g per liter of water, which helps draw out the floral aroma, adds a pleasant tartness, and acts as a natural preservative.

Bring water to a boil in a separate pot, then let it cool for about five minutes until it reaches around 80 degrees Celsius. Water that is too hot can destroy the delicate floral aroma. Pour it over the blossoms so they are completely submerged. If the flowers float to the surface, weigh them down with a small plate or lid.

Cover the container with a clean cloth or cling film and leave to infuse at room temperature for 24 to 48 hours. A shorter infusion gives a lighter, more delicate drink, while a longer steep produces a deeper floral intensity. Stir the mixture gently once a day with a wooden spoon to allow the flavors to develop evenly and prevent the blossoms from settling.

After the infusion period, strain the liquid through a fine sieve lined with muslin or a clean cotton cloth into a clean pot. Squeeze the blossoms and lemon slices firmly by hand or press them with a spoon to extract every last drop of aroma and juice. You will be left with a clear, pale golden liquid ready for the next stage.

Add granulated sugar to the strained liquid and heat over low heat, stirring constantly, until the sugar has fully dissolved. Raise the heat slightly and let the mixture bubble gently for five to seven minutes until it thickens slightly. Avoid boiling it for too long or allowing it to caramelize, as this would dull the fresh floral character.

Skim off any foam from the surface using a spoon or small sieve. Using a funnel, immediately pour the hot liquid into pre-sterilized glass bottles or jars. Seal tightly and turn upside down for about five minutes to sterilize the lids as well, then stand the bottles upright and leave until completely cool.

Dilute the concentrate with still or sparkling water in a ratio of about 1:6 and adjust to your taste. Serve well chilled over ice with a slice of lemon and a sprig of fresh mint.

It also works beautifully as a base for summer cocktails, stirred into salad dressings, or drizzled over pancakes and cottage cheese desserts. Try adding a splash to sparkling water with fresh mint for a simple homemade lemonade.
