Thanks everyone for all the suggestions. In the end I found a cranberry chutney recipe...most expensive component being the cranberries which are on special this week...am cooking it up now, it's a gorgeous colour, it has currants and cloves and ginger in too so a nice Christmassy theme. I am going to do some fancy labels and call it "Christmas in a jar", and trim it with circles of christmas fabric out of my stash.
