A dressing created by emulsifying oil with a red wine vinegar and mustard base is called?

• A. Vinaigrette dressing
• B. Creamy dressing
• C. Marinade
• D. Glaze

Answer: (A)

Emulsifying oil with an acid like red wine vinegar, especially with a small amount of mustard to help stabilize it, creates a vinaigrette-style dressing. The oil and vinegar don’t mix on their own, so the mustard acts as an emulsifier to hold the suspension together and give a smooth, cohesive coating. This is the hallmark of a vinaigrette: a thin, oil-and-vinegar emulsion that clings to greens or vegetables.

Creamy dressings rely on dairy or mayonnaise for thickness, not just oil and vinegar. Marinades flavor foods before cooking, not serve as a finished dressing. Glazes are sweet, sticky coatings used during cooking to build a glossy surface. So the described preparation fits a vinaigrette.
