mayo

Mayonnaise (often abbreviated as mayo) is an emulsified condiment made by whisking together egg yolk, oil, and an acidic ingredient—typically vinegar or lemon juice. The emulsion forms when the lecithin in egg yolk binds the oil and water-based components into a stable, creamy suspension. Traditional mayonnaise is pale yellow to cream-colored with a smooth, thick consistency; modern commercial variants may include stabilizers and preservatives for extended shelf life.\n\nThe ingredient originated in early 18th-century Menorca, Spain, though its exact etymology remains debated. Regional variations exist worldwide, with French-style mayonnaise typically using whole eggs or additional yolks for richness, while lighter versions employ fewer yolks or oil-in-water ratios. Flavored variants (aioli, sriracha mayo, herb-infused) have proliferated in contemporary cuisine.

Mayonnaise functions as both a standalone condiment and a base for compound sauces. It is fundamental in sandwich construction, particularly in American, Japanese, and Northern European cuisines, where it serves as a creamy binder for layered ingredients. In French cooking, mayonnaise forms the foundation for derivative sauces (remoulade, tartare) and is incorporated into composed dishes such as salade niçoise and croquembouche garnishes.\n\nBeyond traditional applications, mayo stabilizes emulsified dressings, enriches composed salads, and provides moisture and cohesion to forcemeats and terrines. It pairs effectively with bold flavors—smoked fish, cured meats, aged cheeses—and serves as a vehicle for flavor infusions (spices, herbs, fermented pastes) in both professional and home kitchens.
