Check elderflowers for dirt and little insects - don't wash!
Add elderflowers, lemon slices and citric acid to the water in a big pan. (The only ingredient not yet going in is the sugar)
Heat up to boiling point, stirring occasionally, remove from heat, cover and let infuse overnight, or for at least four hours.
Strain the liquid through a muslin cloth, to catch all the flowers. Squeeze all that yummy flavour out of the pulp in the muslin!
Return liquid to the pan and add the sugar.
Bring to boil again, stirring frequently to dissolve all the sugar, and simmer for 5 minutes.
In the meantime, sterilise some glass bottles (don't forget about the lids!) with boiling water. If you are going to use a funnel or any other pouring aid, sterilise that, too.
Bottle up the finished cordial while it's still boiling hot.
Depending on desired sweetness, dilute 1:5 to 1:10.
Best enjoyed with sparkling mineral water.
Optional: Squeeze in some fresh lemon for extra tanginess!
