Sumac is the ground spice of an edible round berry, popular in the Levant and Turkey. The crimson spice brings a pop of colour and a savoury lemony fruity note to many dishes. Levantine Arab cooks even use it in lieu of lemons when the latter is unavailable or out of season.
Sumac is brilliant with fish, chicken, or grilled meats. It is also lovely sprinkled on salads, onion dishes, or with toasted pita chips. Use it when you wish to add a sour note to a dry rub without adding liquid from citrus juice.
