I first had this one-pot dish in Tel Aviv, but its flavor notes—a medley of savory, sweet, and sour—are similar to other dishes you’ll see throughout the Middle East. Pistachios browned in butter, sweet nuggets of Medjool dates, and piquant lemon juice bring out the best in lamb and rice seasoned with fragrant cinnamon, nutmeg, and cumin. For the most robust flavor, use a high-quality purchased chicken stock, or, even better, homemade stock.
