mayonesa

Mayonesa (Spanish: mayonesa; English: mayonnaise) is a stable emulsion of egg yolks, neutral oil, and an acid (typically vinegar or lemon juice), with salt and seasonings. The ingredient is believed to derive its name from the port city of Mahón in Menorca, though some sources trace it to a 1756 French victory at that location. The emulsion forms when egg yolks, which contain lecithin (a natural emulsifier), are whisked with oil in a slow, controlled manner, allowing the fat to be dispersed uniformly throughout the aqueous phase. Mayonesa is characterized by its pale yellow, creamy texture and rich, tangy flavor profile. It may be prepared by hand with a whisk or mortar and pestle, or mechanically with food processors and commercial equipment.

Mayonesa is a foundational condiment in Spanish, Latin American, and Mediterranean cuisines, though variations exist worldwide. In Spain and Spanish-speaking countries, mayonesa is often made with local variations in fat content, egg ratios, and acid choices. The ingredient is widely used as a base for other sauces and dressings.

Mayonesa serves as a versatile condiment and sauce base across Spanish, Latin American, and Mediterranean cooking. It is used as a spread for sandwiches, burgers, and tapas; as a binding agent in salads (ensalada rusa, potato salad); and as a base for derivative sauces such as alioli (when garlic is added), salsa golf (mixed with ketchup), and other regional variations. In Spain, it accompanies fried seafood, croquetas, and vegetable dishes. Across Latin America, mayonesa appears in ceviches, empanadas, and various dressed salads. The condiment pairs well with grilled meats, seafood, and raw vegetables, and is essential to numerous cold appetizers and first courses.
