Fran's Fermented Elderflower Soda

Elderberry flower heads

Pick two or three elderflower heads and remove flowers from stems. 

Put six cups of unchlorinated water into a two litre jar. 

Add a heaped tablespoon of honey and stir to dissolve. 

Stir in the elderflowers. 

To speed up the fermenting process you can add a pinch of yeast or some whey from the top of plain yoghurt. 

Put the jar (with no lid) on a kitchen bench so you can give it a quick stir whenever you walk past. 

Place a cloth over the top to keep bugs out. 

Within two to six days, depending on temperature, the mixture will start to bubble. 

Once it has a bit of fizz strain the flowers off and put the soda in
the fridge.
