Easy Classic Elderflower Cordial Recipe

1. Place the sugar in a large saucepan/stockpot or a large Pyrex bowl. Pour the boiling water over and stir until all the sugar has dissolved and let cool.
2. Grate the rind of the lemons with a fine grater and add to the sugar water.
3. Slice the lemons into thick slices and add to the water.
4. Add the citric acid and stir.
5. Finally, add the flower heads to the water and stir again.
6. Cover with a clean cloth and leave to steep for 48 hours.

1. Strain through a clean fine muslin cloth into a clean bowl.
2. Using a funnel, fill sterilized glass bottles (see note below). Seal and store in a cool, dark place (not the refrigerator) for a few weeks or process in a water bath to preserve for longer storage. Another option is to freeze in plastic bottles.
3. Once you open a bottle, it must be stored in the refrigerator.

Note: The cordial is delicious diluted with still or fizzy water or used as a flavoring in ice creams, fruit fools (puréed fruit mixed with whipped cream), and other recipes.

How to Sterilize the Bottles

To sterilize the glass bottles, rinse in the dishwasher, or place in a medium hot oven (300 F/150 C) until the bottles are warmed through but not red-hot. Handle with care.
