Classic Elderflower Cordial

2 1/4 pounds sugar

6 cups boiling water

4 medium lemons (washed)

2 ounces citric acid powder (available over the counter at any pharmacy)

30 large elderflower heads (shaken to remove any insects)

Garnish: lemon slices

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; let cool.

Grate the zest of the lemons with a fine grater and add to the sugar water. Make sure to only grate the yellow and not the white pith.

Slice the lemons into thick slices and add to the water.

Add the citric acid and stir.

Add the flower heads to the water and stir again.

Cover with a clean cloth and leave to steep for 48 hours.

Strain through a clean fine muslin cloth into a clean bowl.

Using a funnel, fill sterilized glass bottles with the liquid.

To serve, pour over ice, garnish with lemon slices, and enjoy.
