Semolina is the name given to coarsely milled durum wheat mainly used in making couscous, pasta, and sweet puddings. The term semolina is also used to designate coarse millings of other varieties of wheat, and sometimes other grains as well.

Durum wheat, also called pasta wheat or macaroni wheat, is a tetraploid species of wheat. It is the second most cultivated species of wheat after common wheat, although it represents only 5% to 8% of global wheat production. It was developed by artificial selection of the domesticated emmer wheat strains formerly grown in Central Europe and the Near East around 7000 BC, which developed a naked, free-threshing form. Like emmer, durum wheat is awned. It is the predominant wheat that grows in the Middle East.
