European elder.
Today I made juice of the Elder's flowerheads. These flowers are commonly used in infusions, giving a very common refreshing drink.
It is so easy to make and so delicious to drink! The only things you need are elderflowers, water, sugar, lemons and citric acid, wait a couple of days and then it is finished!
Last year I tried to make sparkling elderflower 'champagne', but didn't succeed.
