To make a balsamic reduction, choose a high-quality balsamic vinegar that is flavorful and sweet. Pour your balsamic vinegar into a wide, shallow pan and bring to a boil over medium heat. If you want a sweet crunch added to the fruit, you can add the sugar while heating the vinegar, or add it at the end if you prefer. Once the vinegar comes to a boil, lower the heat and let the vinegar simmer for 10-20 minutes. If you’ve added sugar to your vinegar, stir it from time to time to keep it from sticking to the pan. Allow the reduction to cool completely before serving. If you want to learn how to use a balsamic reduction, keep reading!
