Flowery vinegar

The elder blossom is really, really late this year. Our eldest came home excited with the first elderflower heads. Not enough to make her beloved elder lemonade, but just enough to try making elder vinegar. I came across a basic recipe of just leaving flowers in vinegar for a couple of weeks. But I think I make my own variety on our favourite raspberry vinegar. A bit of sugar is added there and I think that makes a vinegar delicious for every salad or sandwich.
