Sumac is a popular spice in the Middle East, which does not get enough attention in the US. Ground sumac is a deep red powder that comes from the red, ripe berries of the sumac bush (related to poison ivy, but definitely not poisonous). It has a very pleasant tart berry flavor, but without the acidity of a fresh lemon. When combined with honey in this recipe, the sumac-spiced chicken has a great balance of sweet and sour.
This recipe is simple yet delicious. Add the honey just before serving as it tends to drip off the edge of the bread. Or if its a casual meal, just pass around the bottle of honey and diners can add their own kiss of honey.
