A staple of North African cuisine, couscous is granular semolina. Cooked, it may be served with milk as porridge, with a dressing as a salad or sweetened and mixed with fruits for dessert. Packaged precooked couscous is available in Middle Eastern markets and large supermarkets. The name couscous also refers to the famous Maghreb dish in which semolina or cracked wheat is steamed in the perforated top part of a special pot called a couscoussière, while chunks of meat (usually lamb or chicken), various vegetables, chickpeas and raisins simmer in the bottom part. In lieu of a couscoussière, a colander set over a large pot will do. The cooked semolina is heaped onto a platter, with the meats and vegetables placed on top. All diners use chunks of bread to scoop the couscous from this central platter. Couscous varies from country to country — Moroccans include saffron, Algerians like to add tomatoes and Tunisians spice theirs up with the hot-pepper-based harissa sauce.
