french salad dressing

French salad dressing, also called vinaigrette or French vinaigrette, is an emulsified or temporarily mixed condiment composed primarily of oil, vinegar, and seasonings. The classic ratio follows the proportion of three parts oil to one part acid (typically wine vinegar or vinegar), with mustard, shallots, and herbs added for flavor and to aid emulsification. The dressing may be prepared as a temporary emulsion that separates upon standing, or as a more stable emulsion using mustard or egg-based binders. Unlike creamy American-style French dressing, authentic French versions remain vinegar-based and lighter in texture, with the oil and vinegar remaining somewhat distinct rather than fully homogenized.

French vinaigrette is primarily used to dress green salads and raw vegetable preparations, though it also serves as a marinade for vegetables, grilled meats, and fish. In French cuisine, vinaigrette functions as a foundational mother sauce from which numerous variations derive, including mustard vinaigrette, herb vinaigrette, and shallot-forward versions. It may be whisked with Dijon mustard to create a more stable emulsion, or thinned with water or stock for lighter applications. The dressing is essential in composed salads (salades composées) and is sometimes spooned warm over vegetables or grains immediately after cooking to enhance absorption of flavors.
