Aioli is a Mediterranean sauce made from garlic, olive oil, and often egg yolks and lemon juice. It has a rich, creamy texture and a strong, garlicky flavor with hints of tanginess from the lemon juice. Aioli is traditionally made by slowly mixing olive oil with crushed garlic, creating a thick and velvety sauce. It is commonly used as a dipping sauce for bread, vegetables, or seafood, as well as a condiment for sandwiches, burgers, and grilled meats.
