Undoubtedly one of the world’s most well-known condiments, mayonnaise is a type of emulsion that’s made by combining egg yolks with oil, lemon juice or vinegar, seasonings, and optional flavorings. Although similar combinations of eggs and olive oil have been part of the ancient Egyptian and Roman cuisines, the version of mayonnaise that we’re all familiar with today was most likely created by one of France’s leading chefs, Marie-Antoine Carême.
Other conflicting stories suggest that the sauce is of Spanish origins, while some claim that it originated from the French cities of Bayonne or Les Mayons. When it comes to mayonnaise’s name, there are also multiple theories behind the word’s evolution.
The original name is believed to have been either mahónnaise, after the Spanish city of Mahón, or bayonnaise, after the French city of Bayonne, and some suggest that it has changed to mayonnaise because of a printing error.
