What’s sumac ?

 This spice comes from the berries of a wild bush that grows wild in all Mediterranean areas, especially in Sicily and southern Italy, and parts of the Middle East, notably Iran. It is an essential ingredient in Arabica, Turkey and the Levant, and especially in Lebanese cuisine. In these areas it is a major souring agent, used where other regions would employ lemon, tamarind or vinegar. It is rubbed on to kebabs before grilling and may be used in this way with fish or chicken. The juice extracted from sumac is popular in salad dressings and marinades and the powdered form is used in stews and vegetable and chicken casseroles.

Sumac is a bushy shrub that has bright red leaves in the fall. It is a relative of poison ivy and can cause skin rashes. This variety grows in Oklahoma and Missouri. I'm sure it's in other states but I don't have personal knowledge of which ones.

A sprinkling of this pretty purple spice adds a tangy lemony flavour to meat and salads.... Prior to the introduction of lemons, the Romans used sumac as a souring agent. It has a pleasant tangy taste with a hint of citrus fruitiness and virtually no aroma.

Sumac is a woody shrub which blooms and produces berries in spikes at the ends of the limbs.  If the berries are white, leave it alone as they can be poisonous.  If the berries are dark red, you can make what we called "Indian lemonade" by cutting off a spike of berries and steeping it in boiling water. 

It is one of the ingredients in a mixture of herbs called Zahtaar that is widely used in the middle east.  My favorite dish with Zahtaar is very simple.  A flat bread spread with a mixture of Zahtaar and Olive oil and then put under the broiler.  Outstanding with Yogurt and Olives.

it is the spice but what everyone has failed to say is that you put it on rice (or at least a lot of Persain families like mine do)

I thought it was a plant that if you came in contact with it you would break out in a rash like poison ivy. Itches like the devil and is hard to get rid of. Can be spread to other parts of the body if the effected places come in contact with your good places. Another word stay away from it if possible.
