Fill a large jar with elderberries, and pour in vegetable glycerine or elderflower glycerite to fill the gaps until the jar is full. Place in a warm spot, on a sunny window ledge or by a range cooker, and leave for two weeks. Strain and squeeze the juice out of the berries, using a jelly bag or a press. Bottle the liquid, label and store in a cool dark place.
This can be used on its own for coughs and sore throats or mixed with cherry bark syrup (see page 25, Hedgerow Medicine).
