The term “tagine” refers to a Moroccan shallow earthenware cooking vessel with a conical lid as well as the stewy dishes prepared in the pot. To make this tagine of tender, warmly spiced meatballs simmered in a thick tomato sauce—a much-simplified version of a dish we tasted in Marrakech—we use a 12-inch skillet with a lid and we bring the pan directly to the table for serving. Ras el hanout is a fragrant Moroccan spice blend that may include more than a dozen different ingredients; it’s an easy way to add complex North African flavors to your cooking. Look for ras el hanout in well-stocked supermarkets, Middle Eastern grocery stores or spice shops. If it’s not available, use 1 tablespoon ground cumin, 1½ teaspoons ground coriander and ½ teaspoon ground cinnamon to achieve a similar warm, savory spiciness.
