Vinaigrette is made by mixing an oil with a mild acid such as vinegar or lemon juice. The mixture can be enhanced with salt, herbs and/or spices. It is used most commonly as a salad dressing, but can also be used as a marinade. Traditionally, a vinaigrette consists of 3 parts oil and 1 part vinegar mixed into a stable emulsion, but the term is also applied to mixtures with different proportions and to unstable emulsions which last only a short time before separating into layered oil and vinegar phases.

Vinegar is an aqueous solution of acetic acid and trace compounds that may include flavorings. Vinegar typically contains from 5% to 18% acetic acid by volume. Usually, the acetic acid is produced by a double fermentation, converting simple sugars to ethanol using yeast and ethanol to acetic acid using acetic acid bacteria. Many types of vinegar are made, depending on source materials. The product is now mainly used in the culinary arts as a flavorful, acidic cooking ingredient or in pickling. Various types are used as condiments or garnishes, including balsamic vinegar and malt vinegar.
