Tagines can be traced back to Harun Al Rashid, a ruler of the Islamic Empire. Tagine-style food was also mentioned in ‘The Thousand and One Nights’. Other stories say that the Roman Empire used portable ovens that function similarly to tagines. Some of these had North African features like fluted lids, which were different from pottery found in Britain. They were used for open fires, just like tagines. Although the vessel is used in Tunisia, tagine is used to describe a different meal on Tunisian menus. This meal is more similar to a frittata than the Moroccan-style meat and vegetable stew. The tagine has evolved with influences from Moorish refugees from Southern Spain, French colonialists and Arab and Ottoman invaders, writes author Ghillie Basan in her book Tagines & Couscous. Traditionally, tagines often include dried fruit like prunes or apricots along with meat. Tagines are best enjoyed with couscous.
