Take ripe barberries, and having stripped them from the stalks,
mash them, and boil them in their juice for a quarter of an hour.
Then squeeze them through a bag: allow to each pint of juice, a
pound of loaf-sugar; and having melted the sugar in the juice,
boil them together twenty or twenty-five minutes, skimming
carefully. Put it up in tumblers with tissue paper.
