There are many recipes for elderflower cordial, but this one is pretty delicious…
Heat 2 pints of water with 3lbs granulated sugar, stirring until completely dissolved. Leave to cool.
Put in a large bowl with another pint of water, 4 sliced oranges, 1 sliced lemon, 2oz citric acid and 25 elderflower heads. Cover
and leave for 24 hours before straining through fine cloth and pour into sterilised bottles. Make sure they are properly sealed
and keep somewhere cool and dark or in the fridge.
