A dish of mine, Chicken with Caramelized Sumac Onions, Preserved Lemon and Pearled Couscous, was featured on Food52 as a superb one-pot meal. Afterwards, a friend of mine told me how much she, too, loves sumac, and asked if I'd ever tried it atop sauteed spinach. I'd not but was immediately intrigued and that evening made this (with chard). For lunch the next day I made this again (using kale and arugula). I ate every bite both times.
