This makes a wonderful glaze for meat or a spread or warm bread. The recipe calls for white balsamic vinegar because it will create a light cover jelly. If you are unable to find it make it with the dark balsamic but the jelly will be darker and have a more robust flavor. Remember when making jellies to not squeeze the jelly bag to speed juice collection, doing so may produce a cloudy jelly. This is from the Ball Complete Book of Home Preserving. The recipe is for under 1,000 feet elevation so adjust it for your area.
