ZATAR, ZAATAR, ZAHTAR
Zatar is an aromatic spice mixture used in the Middle East, especially Turkey, Jordan and North Africa. Like many spice mixtures, there are many variations, but all contain (toasted) white sesame seeds, ground sumac, thyme and salt. It is used on meats and vegetables, and is also mixed with olive oil to make a spread or dip. Zatar has a unique zesty/herby flavor.
Zatar can usually be found in Middle Eastern groceries.
