   5       lb           Currants
   8       lb           Brown sugar
   7       c            White vinegar
   2                    Chunks fresh ginger

   7       ts           Curry powder
   7       ts           Salt

Preparation:

Cook all except sugar. Add sugar to dissolve. Cook and bottle. This is a recipe I used to make up in a restaurant I worked in when we had a glut of blood plums. It is pretty simple but good, especially if left to mature a while in the bottle.
