Orzo is similar to wheat pasta. It is also known as orzo pasta or orzo rice. Initially, orzo was made from barley, but now it is made from wheat or semolina. Semolina flour, which is made from Triticum turgidum wheat grains, gives cooked orzo a hard bite but contains less gluten. When orzo is made from Triticum aestivum or whole-wheat grains, it becomes chewy when cooked and contains more gluten. This rice-shaped wheat pasta is often included in soups and stews. It absorbs the flavor of meats and vegetables it is being cooked with. Orzo grains are thick and bulky. Therefore, when cooked without adding meat or vegetables, it is served in small quantities. These grains can be stored in airtight containers. When cooked, they have to be refrigerated and should be consumed within 2 to 3 days. Orzo pasta or grains are made from wheat, and it is rich in gluten. Therefore, a person suffering from celiac disease or non-celiac gluten sensitivity should strictly avoid consumption. Orzo is good for those who are not sensitive to gluten and want a nutritious carbohydrate diet. Since orzo resembles rice, it can very well be mistaken as rice. Hence, those sensitive to gluten should ascertain the ingredients in their pasta before ordering or consumption. Pasta made from flours of rice, quinoa, lentil, fava beans, white beans, potato, amaranth, and tapioca are gluten-free substitutes for orzo. Couscous can also be a substitute for orzo.
