Fine house-made mayonnaise is one of the glories of the cold kitchen. Considered the mother sauce of garde manger work, mayonnaise is the basis of hundreds of dips, spreads, and dressings.
Mayonnaise is a cool permanent emulsion sauce classically made from vegetable oil, vinegar, and egg yolks. Mayonnaise can be made thick enough to bind the elements of a composed salad, or it can be made thin enough to pour as a sauce. A mayonnaise can act as a bland base for other stronger and more highly seasoned ingredients, or it may be boldly flavored enough to stand on its own.
