Tajine or tagine is a type of dish found in the North African cuisines of Morocco, which is named after the special pot in which it is cooked. The traditional tajine pot is formed entirely of a heavy clay which is sometimes painted or glazed. It consists of two parts; a base unit which is flat and circular with low sides, and a large cone or dome-shaped cover that rests inside the base during cooking. The cover is designed to promote the return of all condensation to the bottom. With the cover removed, the base can be taken to the table for serving.
Moroccan tajines often combine lamb or chicken with a medley of ingredients or seasonings: olives, quinces, apples, pears, apricots, raisins, prunes, dates, nuts, with fresh or preserved lemons, with or without honey, with or without a complexity of spices. Traditional spices that are used to flavour tajines include ground cinnamon, saffron, ginger, turmeric, cumin, paprika, pepper, as well as the famous spice blend Ras el hanout. Some famous tajine dishes are mqualli or emshmel (both are pairings of chicken, olives and citrus fruits, though preparation methods differ), kefta (meatballs in an egg and tomato sauce), and mrouzia (lamb, raisins and almonds).
