Algerian couscous, (Berber languages: ⵙⴽⵙⵓ, romanized: seksu, Arabic: كُسْكُس kuskus; ) – sometimes called kusksi, kseksu, or seksu, is a North African dish that typically consists of semolina granules. There are several regional variations of Algerian couscous, and the specific ingredients and preparation methods can vary depending on the area and the preferences of the cook.

The preparation of Algerian couscous can be a time-consuming process that requires several steps. First, the semolina granules are moistened with water and olive oil and rubbed together until they form small, uniform balls. These balls are then steamed in a keskas, a special pot with a steamer basket on top, for about an hour until they are fluffy and tender. Meanwhile, the meat and vegetables are cooked in a separate pot with spices, such as cumin, coriander, and turmeric. The stew is then combined with the cooked couscous,  and the dish is typically garnished with onions or fresh herbs, such as parsley or cilantro.

Etymology 
According to the Algerian linguist Salem Chaker, the origin of the word "couscous" is most likely Berber. The base form of the word, "seksu," along with its phonetic variations, is attested in various Berber dialects. The Saharan Berber dialects, including Touareg and Ghadames, have a slightly different form, "keskesu." The widespread geographical dispersion of the term strongly suggests a local berber origin.

The Berber root *KS signifies qualities such as being well formed, well rolled, and rounded.

Origin 
According to food historian Lucie Bolens, couscous has its roots in ancient times, specifically during the reign of Masinissa in the ancient kingdom of Numidia, located in present-day Algeria. Traces of cooking vessels similar to couscoussiers have been discovered in graves dating back to the 3rd century BC, which belonged to the Berber kings of Numidia. These archaeological findings were unearthed in Tiaret and Kabylia, Algeria. The Cirta Museum in Constantine, Algeria, preserves these historical utensils.
