Elderflower Cordial

Wash the lemons thoroughly and slice them.

Gently wash the elderflower heads and let them drain well.

Put the elderflowers and lemon slices into a large container, add 7 liters of water, add the sugar and citric acid and stir until the sugar is completely dissolved.

Cover the container with a clean cloth and leave to infuse overnight.

Stir again the next day and strain the cordial through a fine sieve or cloth.

Pour into clean bottles and seal well.

For a sparkling version, place the sealed bottles in a dark place and let them mature for at least 6 weeks.
