Aioli is a Mediterranean sauce that traditionally consists of garlic and olive oil. It can also include other ingredients such as egg yolk, lemon juice, and mustard, depending on the recipe. True aioli is an emulsion of mashed garlic, olive oil, and a pinch of salt, and making it can be laborious, as the oil needs to be added slowly while pounding it together with a mortar and pestle
. In some regions, the term "aioli" is used interchangeably with mayonnaise, but traditionally, aioli is distinguished by its strong garlic flavor and the use of olive oil
