@spendius,
Wiki, that stallwart group function, says this about tajine/tagine:
http://en.wikipedia.org/wiki/Tajine
A tajine or tagine(Arabic: طاجين tajin from the Persian: تابه tabe[1]) is a historically Berber[2] dish from North Africa that is named after the special earthenware pot in which it is cooked. A similar dish, known as tavvas, is found in the cuisine of Cyprus. 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 that is flat and circular with low sides and a large cone- or dome-shaped cover that sits on 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. Tajines are also used and made in Morocco.
More recently,[when?] European manufacturers have created tajines with heavy cast-iron bottoms that can be heated on a cooking stove to a high temperature.[citation needed] This permits the browning of meat and vegetables before cooking.
A tagine is a unique type of ceramic or clay cookware that's popular in Morocco. The bottom is a wide, circular shallow dish used for both cooking and serving, while the top of the tagine is distinctively shaped into a rounded dome or cone.
The word "tagine" also refers to the succulent dish which is slow-cooked inside the cooking vessel. Typically, a tagine is a rich stew of meat, chicken, or fish, and most often includes vegetables or fruit. Vegetables can also be cooked alone. Although tagines are traditionally made of clay or ceramic, some Western cookware companies are now making tagines from other materials. The use of ceramics in Moroccan cooking is probably a Roman influence. Romans were known for their ceramics, and likely brought that tradition to their rule of Roman Africa.
Ceramic tagines are exquisite examples of Moroccan artisanship, and many are show pieces as well as functional cooking vessels. Some tagines, however, are intended only to be used as decorative serving dishes.
Unglazed clay tagines are favored by some for the unique earthy nuance they impart to dishes. Like their glazed counterparts, they come in all sizes. The smallest might hold enough food for one or two people, while the largest can hold a meal for eight people or more. Moroccan Tagines or Stews
Tagines are primarily used to slow-cook savory stews and vegetable dishes. Because the domed or cone-shaped lid of the tagine traps steam and returns the condensed liquid to the pot, a minimal amount of water is needed to cook meats and vegetables to buttery-tenderness. This method of cooking is very practical in areas where water supplies are limited or where public water is not yet available.
