- Place the elderflower heads and lemon rinds in a large bowl. I cut a lot of the green stalks off as they can add bitterness.
- Boil the water and pour over the elderflower, cover and leave overnight.
- Strain the liquid through a fine sieve or a piece of muslin (I use a cotton pillow case that I bought to do this).
- Bring the liquid to the boil in a pan with the sugar, citric acid and lemon juice and boil for 2 minutes.
- Allow to cool before filling sterilised bottles.
As well as using as a drink, the cordial can be used to flavour desserts too. It lasts for about 3 months. Once opened keep in the fridge.
Some recipes don’t soak the elderflower overnight and just boil the ingredients for about 30 minutes. I prefer to do it this way. My tastes have changed over the years and I have reduced the sugar content and I often replace half of it with Stevia so that it is more healthy.
The lady in the garden behind me has a black elderflower which has pink flowers. Some is hanging over my garden and so I am going to ask if I can have some flower heads to give mine a pink tinge this year.
