Twelfth-century couscoussiers were found in the ruins of Igiliz, a Moroccan archaeological site.
A couscoussier is a vessel designed for steaming couscous, normally with a perforated upper section placed over a pot of simmering liquid or stew. Finding such equipment in Igiliz provides material evidence that couscous preparation was part of domestic life in the medieval Sous region, rather than merely a modern national symbol.
Igiliz is a medieval settlement in the Anti-Atlas on the edge of the Sous valley. It is especially significant because it is associated with Ibn Tumart, the founder of the Almohad movement. Archaeologists have recovered a range of household ceramics there, including jars, lamps, plates, braziers, cooking pots, a bread oven and couscoussiers.
The alternatives are also genuine Moroccan archaeological sites, which makes the question challenging. Cotta and Lixus are strongly associated with ancient Roman-period fish processing, while Volubilis is famous for its Roman ruins and mosaics. The specific clue is the twelfth-century cooking equipment: that points to Igiliz.
