Which statement best defines a vinaigrette?

• A. An oil-and-acid emulsion seasoned with aromatics
• B. A thick dairy sauce
• C. A heavy tomato-based sauce
• D. A chocolate glaze

Answer: (A)

Vinaigrette is a dressing formed from oil and an acid, such as vinegar or citrus juice, that is whisked or shaken to form a light emulsion and is seasoned with aromatics like mustard, garlic, herbs, salt, and pepper. The key idea is that fat and acid come together into a stable coating that lightly clings to greens, delivering a balance of brightness from the acid and richness from the oil. That best matches the description of an oil-and-acid emulsion seasoned with aromatics. The other options describe a thick dairy sauce, a heavy tomato-based sauce, or a chocolate glaze, which are not vinaigrettes in ingredients or texture.
