A vinaigrette is a simple dressing made primarily from oil and vinegar, often used to enhance salads and vegetables. The basic ratio is three parts oil to one part vinegar, but you can adjust it to suit your taste. Many people like to add seasonings like salt, pepper, or herbs to create different flavors. Vinaigrettes can be customized with various ingredients, such as mustard, honey, or citrus juice, to add depth and complexity. This versatile dressing not only adds flavor but also helps to balance the freshness of greens, making it a popular choice for healthy meals.
