The name of this dish comes from the vessel it was traditionally cooked in - a flat-sided unglazed earthenware dish with a tight-fitting conical lid - a tagine. But don't be put off making this amazing Moroccan stew if you don't have a tagine to cook it in. You can make it perfectly well in a casserole dish, dutch oven, stockpot, crockpot or slow cooker. Traditionally it would be cooked in the embers of a fire, but these days you can do it on your stovetop or in your oven.
Olive oil for sautéeing. Chopped fresh coriander (cilantro) and finely sliced preserved lemon to garnish.
