The elderflower wine recipe is a little more complicated (recipes are easily available online) but the ingredients are the same as for cordial - flowers, lemon, sugar and water!
Wild roses are also in bloom on hedgerows everywhere. This is our wild rose bush that we brought with us from Kerry in 1996 and now happily resides beside the fuschia hedge in our front garden.
I love wild roses. Ours are pink, but they also are abundant in white. The pink petals are preferable for a cordial just because the end product looks nice!
To make the cordial, you need about 2 generous handfuls of petals with bitter white "claws" removed, juice of 1 lemon, 500 ml water and 300 g sugar. Simmer water, petals and lemon juice for 15 mins. Strain and return liquid to pot; add sugar to the rose water and heat till sugar has dissolved. Simmer 5 mins before filling sterilised bottles or jars.
Add sparkling water to the cordial for a soft drink, or add prosecco for a sparkly adult drink. Better yet, make rose petal martinis and enjoy the great weather!
