Sparkling Elderflower Wine - cooking recipe

Ingredients

10 bunches elderberry flowers (an umbel is a flower cluster all starting from the same point, literally a little umbrella)
1 lemon
350 ml water
8 tablespoons apple cider vinegar
4 tablespoons honey
1 lemon, juice of

Preparation

Rinse the elderberry flowers- they must be just in bloom.
Cut the lemon into thin slices and mix with the flowers and the remaining ingredients in a reasonably large container.
Stir.
Cover the container and leave in a warm place.
The juice can be drunk after 24 hours.
If necessary add lemon and honey to taste.
After 2-3 days the drink will begin to effervesce.
