Sumac, a seed from a bush of the same name, stands out for its brown color and sour taste. Essential in Oriental cuisine, it replaces tamarind, lemon, and vinegar, adding acidity to sauces and blends. With an intoxicating aroma, it holds symbolic meaning: it is one of the seven "S" during the Iranian New Year, where it is offered on the family table as a synonym for "good life." The product comes in a convenient format.
