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.

Can You Freeze Mayonnaise-Based Salads?

Freezing salads that contain mayonnaise is not a good idea. The ingredients in mayonnaise do not bind well during freezing and neither do they keep salad condiments together. So, when the salad thaws, it is less appetizing and has a not-so-good taste.
