nayonaise

Mayonnaise is an emulsified condiment made from oil, egg yolks, and an acidic ingredient (typically vinegar or lemon juice), with mustard often included as both a flavoring agent and emulsifier. The term derives from the French "sauce mahonnaise," possibly originating from Mahon, the capital of Minorca. The ingredient is fundamentally an oil-in-water emulsion, where lecithin from egg yolks acts as the emulsifying agent, allowing fat and aqueous components to remain suspended in a stable, creamy suspension.

The emulsification process requires whisking oil into egg yolk very gradually while maintaining constant agitation; premature addition of oil causes the emulsion to break. Traditional mayonnaise has a pale yellow to cream color, glossy appearance, and rich, slightly tangy flavor. Commercial variants may include additional stabilizers (xanthan gum, starch) and preservatives (potassium sorbate). Regional variations exist worldwide, such as Japanese Kewpie (made with whole egg and rice vinegar) and Spanish Mahonesa.

Mayonnaise serves as both a condiment and a base for derivative sauces across global cuisines. It functions as a sandwich spread, a dressing component for salads and slaws, and a binding agent in composed dishes such as croquettes, deviled eggs, and tuna or chicken salads. In classical French cuisine, mayonnaise is the foundation for aioli, remoulade, and béarnaise variations. It appears in Asian fusion cuisine (notably Kewpie mayo in sushi preparations), and as a topping in Spanish pintxos and Russian salads. Mayonnaise pairs particularly well with cold preparations, grilled vegetables, and seafood. It should be stored refrigerated after opening and used within 2-3 months once prepared at home.
