  • About
A vinaigrette is much like a mayonnaise, in that it is the emulsion of an acidic ingredient with oil. While mayonnaise is emulsified with egg yolk, a vinaigrette is emulsified with mustard—at least traditionally Because mustard is a less stable emulsifier than mayonnaise, a vinaigrette can separate if made too far in advance or if stored overnight in the refrigerator.

The secret to a successful vinaigrette is to use the best possible oils and vinegars. Homemade vinegar is great if you have it (see), but you can also use good-quality commercial vinegar, such as sherry vinegar or balsamic vinegar. Extra virgin olive oil equals wine in variety and complexity of flavor, so it is worth experimenting to find your favorites. Some vinaigrettes are made with bland oils, such as canola oil or grape seed oil, when they are being used for dishes so delicate that a stronger oil would interfere. Nut oils are delicious in vinaigrettes used on bitter greens, but they are so strongly flavored (at least good ones) and expensive that it is usually best to combine them with a flavorless oil.
