This dried sour berry of the sumac shrub is used widely in Eastern Mediterranean cuisines, and is a prominent flavor in Za'atar. Sprinkle this seasoning on hummus, a cucumber tomato salad or on grilled meats with sliced onions. It could even be a secret ingredient in this year's holiday candy! We also love pairing sumac in a Strawberry and Vanilla Bean Cheesecake Trifle for the ultimate no-bake summer treat, or braising it with Pomegranate Chicken for an easy entree. INGREDIENTS: Sumac and Salt.
