The flowers of the elderberry can also be eaten and made into
tea,
wine or
syrup.
Elderberry flowers can be eaten straight off the branches (check for bugs though!) or you can make fritters out of them. To do this, pick complete flower heads and wash and drain these. Dip the flowers into batter (pancake batter will do nicely) and bake them flower side down in a little oil in a frying pan until they are crisp. Eat them with powdered sugar.
Elderflower syrup is made by boiling the flowers (without stems) with water and sugar, then straining the mixture. Unfortunately I haven't been able to find a more exact recipe, but it's available at IKEA's Swedish shop, at least in the Netherlands... Elderflower syrup with water makes a refreshing drink that's rather subtle and flowery in taste.
