Wash the elderberries and strip them from their stalks. Wash the blackberries and remove any stems and unripe berries. Mix the two fruits together and simmer for about 20 minutes, crushing the berries with a wooden spoon to release the juices. When the fruit is tender, stir in the sugar over low heat until dissolved. Boil hard to setting point, pour into hot jars and cover.
