Zahtar refers to a spice Blend which consists of sesame seeds mixed with powdered Sumac and dried thyme which is prized for its tangy and distinctive zesty flavor. To use it, Zahtar is usually sprinkled over meats and vegetables, or mixed with oil (olive oil) to form a paste which is then used as a spread for bread (Pita, toast). Zahtar is found in Middle Eastern markets. It is a favorite spice Blend throughout North Africa, Turkey and the Middle East.
