Orzo is a type of pasta that is shaped like a large grain of rice. It is traditionally made from flour, but it can also be made of whole grain or semolina, a type of flour made from durum wheat. Orzo is categorized as a "pastina" or "little pasta" in Italy, and it is often used in Mediterranean dishes such as pastas, pasta salads, soups, stews, and casseroles. Orzo can be colored by saffron, chilies, and black beans to yield yellow, orange, or black pasta. It is also a good source of protein and has a firm texture that maintains its shape when mixed with other ingredients. To cook orzo, it is boiled in salted water until al dente, which typically takes around 8-10 minutes.
