Definition: Aioli

This week's culinary definition is aioli.

Aioli is a Provençal traditional sauce made of garlic, olive oil, lemon juice, and egg yolks. There are many variations, such as the addition of mustard. It is usually served at room temperature. The name comes from Provençal alh 'garlic' + òli 'oil.'

Aioli is like mayonnaise, an emulsion or a suspension of small globules of oil and oil-soluble compounds in water and water-soluble compounds. Egg yolk can be used as an emulsifier and is generally used in making aioli. However, mustard and garlic both have emulsion-producing properties and some variants omit the egg.

Generally, egg yolks, garlic and Dijon mustard (if adding this as a common variation on the basic aioli) are combined first with a whisk, then the oil and the lemon juice are added slowly with whisking to create the emulsion. The additions of the dissimilar ingredients must be slow to start and then can be faster once the initial emulsion has formed.
