The primary function of a salad dressing in a salad is to provide flavor. Dressings enhance the overall taste of the salad by adding acidity, sweetness, creaminess, or savory elements, which can elevate the flavors of the fresh ingredients. The right dressing can create a harmonious balance among the various components of the salad, making it more enjoyable and appealing to the palate.
