Mayonnaise has one of the most contested etymologies of any common food word, with at least four competing theories and no conclusive evidence for any of them. The debate has occupied food historians, linguists, and culinary writers for over two centuries, and it shows no sign of resolution.
The most popular story connects the word to the port city of Mahón (Maó in Catalan) on the island of Menorca in the Spanish Balearic Islands. In 1756, French forces under the Duc de Richelieu captured Mahón from the British during the Seven Years' War. According to legend, Richelieu's personal chef created the sauce to celebrate the victory, either adapting a local Menorcan sauce or inventing something new from available ingredients (eggs and olive oil being plentiful on the island). The sauce was
This story is appealing and widely repeated, but it has problems. The earliest printed recipes for the sauce postdate the battle by several decades, and there is no contemporary account linking Richelieu's chef to a new sauce. The earliest French spelling varies: mahonnaise, mayonnaise, and bayonnaise all appear in early cookbooks, the last suggesting a possible connection to Bayonne, a city in southwestern France also known for fine cuisine.
A second theory derives mayonnaise from the French verb manier, meaning to handle, stir, or work with the hands. This would make it a sauce defined by its method of preparation, the careful, continuous stirring required to emulsify oil and egg yolk. The word maniement (handling) could plausibly have produced a culinary term, and this theory has the advantage of explaining the name through technique rather than geography.
A third theory connects the word to moyeu or moyeux, an Old French word for egg yolk, from the Latin medius (middle), referring to the yolk as the middle of the egg. A sauce based on egg yolks might naturally have been called a moyeunaise or similar form. This theory has linguistic plausibility but lacks documentary support.
The fourth and least supported theory attributes the word to the town of Mahon in general, not through military conquest but through trade. Menorca had long been known for its sauces and olive oil, and a sauce named for its port of origin would follow established culinary naming conventions.
What is beyond dispute is the sauce's basic composition and the remarkable chemistry it embodies. Mayonnaise is an emulsion, a stable suspension of oil droplets in a water-based medium. The egg yolk serves as the emulsifier, its lecithin molecules bridging the oil and water phases. The process requires adding oil very slowly to a beaten yolk while
Mayonnaise entered English cookbooks in the early nineteenth century. By the late nineteenth century it had become a staple condiment in both European and American cuisine. Richard Hellmann began selling it commercially in New York City in 1905, and Best Foods began West Coast production around the same time. Hellmann's and Best Foods, now owned by the same company, remain the dominant commercial brands in the United
The abbreviated form mayo, which appeared by the 1930s, has largely replaced the full word in casual speech, at least in American English. British English tends to retain mayonnaise more often. The word has been borrowed into virtually every language with a food vocabulary, usually with minimal adaptation.
Mayonnaise occupies a curious cultural position. It is simultaneously one of the most widely consumed condiments in the world and a frequent target of passionate hatred. Few foods inspire as much declared disgust. This polarization has made mayonnaise a reliable subject for internet arguments and opinion pieces, ensuring that the word, whatever its origin, remains in constant circulation.
