Which ingredient is NOT typically found in Aioli?

Aioli is a traditional Mediterranean sauce that is primarily made from a few key ingredients. The main ingredients in classic aioli typically include garlic, olive oil, and sometimes egg, which serves as an emulsifier, and lemon juice for acidity and flavor enhancement.

Basil, while it can be a flavorful herb used in various dishes and sauces, is not a traditional component of aioli. The core essence of aioli is its strong garlic flavor, combined with the richness of olive oil, rather than the herbal notes that basil would introduce. Thus, basil does not belong in the standard formulation of this sauce, making it the correct answer in this context.
