Semolina is the coarse, purified wheat middlings of durum wheat used in making pasta, breakfast cereals, puddings, and couscous. The term semolina is also used to designate coarse middlings from other varieties of wheat, and from other grains, such as rice and maize. As an alternative to corn meal, semolina can be used to flour the baking surface to prevent sticking. In bread making, a small proportion of durum semolina added to the usual mix of flour is said to produce a tasty crust. Semolina is a common food in West Africa, especially among Nigerians. It is eaten as either lunch or dinner with stew or soup. It is prepared just like eba (cassava flour) or fufu with water and boiled for 5 to 10 minutes.
