What is the primary ingredient in a traditional vinaigrette?

The primary ingredient in a traditional vinaigrette is oil and vinegar. A vinaigrette is an emulsion made by blending these two components, typically in a ratio of three parts oil to one part vinegar. The oil provides richness and smoothness, while vinegar adds acidity and tanginess, creating a balanced dressing that enhances the flavor of salads and other dishes.

The importance of this oil and vinegar combination lies in its versatility; various types of oils (like olive oil, canola oil, or sesame oil) and vinegars (like balsamic, red wine, or apple cider vinegar) can be used to create different flavor profiles. Although additional ingredients, such as mustard, herbs, or seasonings, can be incorporated for added complexity, they are considered flavor enhancers rather than the core components of a traditional vinaigrette.
