Blackberry Cordial

Put half a gallon of blackberries into a preserving pan with 3 tablespoons of water. Set over a slow heat stirring fairly frequently until the fruit is a pulp. Strain through a sieve or muslin bag. Measure the juice, return to the pan and to each quart add one pound of white sugar. Put 1 tablespoon each of cloves, allspice, cinnamon and nutmeg into a small muslin bag and add to the mixture. Boil for quarter of an hour stirring constantly. Remove the spices, add a wineglass of Rum or Brandy. Allow the cordial to cool then bottle and cork tightly.
