Mayonnaise

Mayonnaise is an emulsion of oil, egg yolk, and an acid, either vinegar or lemon juice; there are many variants using additional flavorings. The color varies from near-white to pale yellow, and its texture from a light cream to a thick gel.

Commercial eggless imitations are made for those who avoid chicken eggs because of egg allergies, to limit dietary cholesterol, or because they are vegans.
