Dressing:

With dressing, we refer to a condiment based on a creamy sauce, usually used to enrich dishes like salad, meat, or fish.

Unlike other condiments like vinaigrette (obtained by emulsifying liquid ingredients such as oil, vinegar, and lemon juice), it has the peculiarity of being creamy, often based on oil, yogurt, egg, and vinegar.

In this case, it is tahini, which is a sauce made from toasted sesame seeds ground with oil, preferably sesame oil, until it becomes a paste; the main ingredient of hummus and babaganoush.
