Balsamic reduction is a cooking technique that involves simmering balsamic vinegar until it thickens and becomes syrupy. This process concentrates the flavors, resulting in a sweet and tangy sauce that can enhance various dishes. Typically used as a drizzle over salads, grilled vegetables, or meats, balsamic reduction adds a rich depth to meals. It can also be used as a finishing touch for desserts, such as strawberries or ice cream, providing a unique flavor contrast.
