What Is Mayonnaise?

Simply put, mayonnaise or mayo is an emulsion of oil, egg yolk, lemon juice (which could be vinegar is some mayo), and other additives. An emulsion is a mixture of two liquids that won’t mix naturally but in mayonnaise, the egg yolk is the emulsifier that makes everything bind into a creamy sauce.
