Description

A “premium vinaigrette sauce” is a high-quality salad dressing made primarily from an edible oil (such as olive oil) and a mild acid (vinegar or lemon juice), often enhanced with various herbs, spices, and other flavorings. 

General Description (for a 100g serving)
A premium vinaigrette is typically characterized by a smooth, rich texture when emulsified, offering a harmonious balance of tangy, savory, and sometimes slightly sweet flavors. The “premium” quality often implies the use of high-quality, natural ingredients, and the absence of artificial colors, flavors, or preservatives. 
Key characteristics for a typical 100g serving:
Flavor Profile: A blend of sharp acidity from the vinegar and the richness of the oil, often with added notes from herbs (like oregano or basil), mustard, or honey for complexity.
Texture: A smooth, glossy, water-based or oil-based liquid that may require shaking or whisking before use, as the oil and vinegar layers naturally separate over time.
Use Cases: It is most commonly used as a versatile salad dressing but also works effectively as a marinade for meats and vegetables, or as a flavorful dip for snacks.
Nutritional Information (Approximate per 100g): A standard vinaigrette typically contains around 291 calories per 100g, with most of the calories coming from fat, though fat-free options are also available. It is generally low in protein and carbohydrates.
