Alioli (often called "Aioli" In english) is one of the most common spanish sauces. The original recipe is said to have originated in catalonia in the northeast of the country on the border of france. The fame of alioli has spread all over spain and is a popular sauce for a variety of traditional foods. The name alioli comes from the catalan words for the two main ingredients all (garlic), i (and), and oli (oil). It is quick, easy, and very flavorful, so it is easy to understand why it is so popular in spain. Serve it with meats, fish, or vegetables; or just spread it on bread. The spanish also use it as an ingredient in main course recipes. This recipe uses two egg yolks, which makes it bind easier. Traditional recipes omit the egg, which makes the emulsion more difficult to achieve.
