real mayonnaise

Mayonnaise is a stable emulsion of oil, egg yolk, and acid (typically vinegar or lemon juice), often with added seasonings. The ingredient originated in 18th-century France, with its name traditionally attributed to Port Mahón on the island of Menorca. The foundation of mayonnaise is the egg yolk, whose lecithin acts as an emulsifier, allowing oil to be incorporated gradually until a thick, creamy suspension forms. True or "real" mayonnaise requires no starch or stabilizing agents—the emulsion depends entirely on proper technique and ingredient ratios. The standard ratio is approximately 1 part egg yolk to 200-300 parts oil by weight, with acid added to taste and preservation. The result is a pale yellow to ivory condiment with a rich, slightly tangy flavor and silky texture, though variations exist regarding oil type, vinegar choice, and seasoning profiles across regions.

Mayonnaise serves as both a finished condiment and a base for numerous derivative sauces in Western, particularly French, cuisine. It functions as a sandwich spread, a dressing for salads and cold vegetables, a component in composed dishes (egg salad, tuna salad, potato salad), and a base for aioli, remoulade, and other emulsified sauces. In classical French cookery, it anchors both simple applications and elaborate preparations. The ingredient requires careful temperature control during preparation—both oil and egg should be at room temperature—and gentle whisking to maintain emulsification. Flavoring variations include mustard (mustard mayonnaise), garlic (aioli-style), herbs, and spices. Quality mayonnaise enhances without overwhelming, making it essential in delicatessens, fine dining, and home cooking across Europe and North America.
