Found this while looking at a list of 'autumn' sarnie ideas on MSN. I thought it might be a different use for the blackberries that there still seem to be a lot of around here:
2 teaspoons cooking oil
1 large apple, peeled, cored, and finely chopped
3 tablespoons minced shallots
2 teaspoon brown sugar
1/8 teaspoon ground cloves
1 cup blackberries
For relish, in a medium skillet heat oil. Cook apple, shallots, brown sugar, and cloves in the hot oil, uncovered, over medium heat for 3 minutes or until just tender. Add blackberries; reduce heat. Cook mixture, uncovered, for 5 minutes, stirring often. Cool. Cover and chill, if desired.
That is just part of the full recipe from here - lamb steak/chop burger with watercress:
