While acid is essential for enhancing flavors in pasta salad, leaning too heavily on vinegar can be a mistake. Instead, use a richer, creamier, more fat-based dressing.
This means using an olive-oil based sauce, with vinegar added as needed. This way, your pasta salad will ultimately be more balanced, satisfying, and well-rounded in flavor.
For a foolproof fresh dressing that’s not overpoweringly tangy, start with olive oil and use at least a 2:1 fat-to-acid ratio. You can adjust ingredients as needed.
You can also adjust the type of vinegar you're using, opting for less harsh, acerbic options like white or rice vinegars, some spritzes of lemon juice, or even pickle juice.
