The traditional version of this classic Moroccan stew is made with homemade preserved lemons and involves a long cooking time. We've simplified the recipe by using lemon rind and juice to achieve the same subtle lemon flavor. Ours is also slow-simmered to yield a rich broth like the original's, but it's made in a fraction of the time. Since this dish is so saucy, it's best served over couscous.
