This spice blend is used in many Middle Eastern cuisines. Depending on the country in which this spice mix is prepared, there may be variations of the spices included.
This spice mix is used in many Middle Eastern cuisines to flavor meat, poultry and fish and soups. It can also be used as a condiment to give a dish a little extra kick after the meal is prepared. This spice blend can be used before grilling, in lentil dishes, or even eggplant.
Buy premixed and packaged or create your own mix using the spices mentioned above.
As with all ground spices, they should only be stored for 6 months. After this period, the ground spices lose a lot of flavor.
