Try substituting sumac powder in any dish on which you might squeeze fresh lemon juice. If you enjoy hummus, try topping it with a sprinkling of sumac. It's delightful!
Sumac once served as the tart, acidic element in cooking prior to the introduction of lemons by the Romans. Sumac has a very nice, fruity-tart flavor which is not quite as overpowering as lemon.
Sumac powder contains a pinch of salt.
