Sumac is derived from the berries of the rhus coriaria tree (sumac tree), native to East Asia, Mediterranean, and the Americas. 

Sumac has a pungent tart, tangy lemony taste and aroma, due to malic acid found in the sumac berries. This makes it a great alternative to citric acid and vinegar for giving food a distinct sour taste. 

Sumac is heavily used in Persian, Middle Eastern and Mediterranean cuisine as a dry rub, in marinades, sauces and dressing.
