Citrus vinaigrette is a type of salad dressing made with citrus juice, vinegar, and oil. It is commonly used on green salads, but can also be used on fruits or as a marinade. The acidity of the citrus juice helps to balance the flavors of the vinegar and oil, while the oil helps to coat the salad and prevents the dressing from separating. Citrus vinaigrettes can be made with any type of citrus juice, but lemon and lime are the most common.
