Sumac

What it is

A coarse, deep crimson-purple powder ground from the dried berries of the sumac shrub (Rhus coriaria). A single-ingredient spice, but a defining one across the Levant, Turkey, and Iran, and a core component of za'atar.

How it's made

The ripe red drupes (berries) are harvested, dried, and ground — sometimes mixed with a little salt. The powder is the whole crushed fruit, including its tart, resinous coating.

Flavor profile

Bright, tart, and lemony with a subtle fruity, astringent, slightly woody depth. Tangy without the liquid of lemon juice — a dry acid.

Culinary uses

Sprinkled over hummus, grilled meats, fish, salads (essential in fattoush), rice, onions, and eggs; a key element of za'atar; rubbed onto kebabs. How to use: almost always a finishing seasoning — its bright acidity is added after cooking to lift a dish; prolonged heat dulls it.

Regional variations

Turkish, Levantine, and Iranian sumacs differ in tartness and color; Iranian sumac (often served alongside kebab) tends to be darker and more intense. Quality hinges on whether it's pure berry or cut with salt.

Cultural & historical context

Used since antiquity as a souring agent before lemons were common in the region — Roman cooks used it, and it remains the everyday acid of much Middle Eastern cooking. (Note: culinary sumac Rhus coriaria is unrelated to the toxic poison sumac of North America.)

Sourcing notes Widely available; the best is a vivid, almost moist crimson rather than a dull brown (dullness signals age or over-salting). Whole-berry, freshly ground sumac from a Middle Eastern grocer is far superior to faded supermarket versions.
