Which of the following is a true characteristic of vinaigrette dressings?

• A. They are typically thin emulsions made from oil and acid
• B. They are thick dairy sauces
• C. They are served warm
• D. They contain equal parts oil and water

Answer: (A)

Vinaigrettes are oil-and-acid dressings that form a thin emulsion. The two main ingredients are oil and an acid such as vinegar or citrus juice, often whisked or shaken with a small amount of emulsifier like mustard to help them stay mixed briefly. This creates a light, pourable dressing that coats greens without being heavy. They are not thick dairy sauces, which rely on dairy products for texture. They’re typically served cold or at room temperature, since heat can cause the emulsion to break. Water isn’t a primary component in vinaigrettes, and the usual balance favors more oil than acid, resulting in a slick, oil-based dressing rather than an equal-part oil-and-water mixture.
