If you want to make a store-bought jar of Alfredo taste more complex and tasty, try adding half a tablespoon of white balsamic vinegar to the sauce while heating it up in the pan.
White balsamic has a taste that’s cleaner and less sweet than regular balsamic, with bright, sometimes slightly floral notes. It can also cut through your Alfredo sauce’s richness.
White balsamic vinegar imparts light yet complex flavors, taking one-note store-bought Alfredo to another level without overwhelming it or adding color to the otherwise pale sauce.
