White Wine Vinegar (Best Option)
1 tablespoon per 1 tablespoon lemon juiceWhite wine vinegar contains acetic acid, which mimics the acidity level of lemon juice, essential for balancing flavors in soup. The mild fruity undertones complement savory ingredients without overpowering them.
When using white wine vinegar, add gradually and taste as you go to avoid excessive acidity. It integrates well into both clear and creamy soups.
Compared to lemon juice, white wine vinegar offers a slightly different but equally effective acidity profile, preserving the soup’s bright and fresh character.
