Homemade elderflower cordial is so much better than anything you can buy. Serve with sparkling water for a refreshing drink or sparkling wine for a delicious cocktail.
Gently rinse over the elderflowers to remove any dirt or little creatures.
Pour the boiling water over the sugar in a very large mixing bowl. Stir well and leave to cool.
Add the citric acid, the orange and lemon slices, and then the flowers.
Leave in a cool place for 24 hours, stirring occasionally.
Strain through some muslin and transfer to sterilised bottles.
