What is sumac? I have a recipe that calls for it, but it is not at my grocery store.
Sumac is a spice, used mostly in Middle Eastern cooking, that has a lovely tart mild lemon flavor. The deep red berries are most often used ground into a powder. I often sprinkle it over a platter of grilled vegetables or roasted chicken; it looks as appealing as it tastes.
These Persian Street Vendor Kebabs are one example of a recipe that uses sumac.
