Use in salad dressings and marinades.
Makes 1 quart
4 cups frozen unsweetened blackberries or black currants, thawed and drained
4 cups red wine vinegar
2 cups red wine
Lightly mash the fruit in a bowl. Add vinegar and wine. Cover and refrigerate overnight. In a non-reactive saucepan, bring mixture to a boil and cook uncovered for 3 minutes. Cool. Strain mixture through a fine sieve lined with several layers of cheesecloth (or a cone shaped coffee filter). The cheesecloth or filter will have to changed several times. Discard solids. Pour vinegar into bottles. Store in a cool dark place.
NOTE:
You can use home frozen berries if you have them.
