5 qts. blackberries
2 cups water
Apple juice
Look over the berries carefully; put them, with the water, into a
cooker-pail and let them come to a boil. Put them in a cooker for three
hours or more, then pour them into a jelly bag and let them drip for a
least six hours. To each cupful of juice add half a cupful of apple
juice prepared as for apple jelly. Boil these juices for fifteen
minutes, then add five cups of sugar to each six cups of juice and boil
it for five minutes longer or until a drop will jelly on a cold plate if
left for a few minutes. Pour it into glasses and seal it when cold, as
directed for apple jelly.
