Noodles are a type of food typically made from unleavened dough which is rolled flat and cut, stretched, or extruded into long strips or strings. Noodles are a staple food in many cultures and made into a variety of shapes. The most common noodles are those derived from Chinese cuisine or Italian cuisine. Italian noodles are generally referred to as pasta. In Chinese cuisine, the overarching term for noodles is 面 (miàn in Mandarin), which refers specifically to dough-based noodles made from wheat or other grain-based dough. Chinese noodles also include another category, called 粉 (fěn), which are not made by kneading dough but from a starch slurry, such as rice noodles (mǐfěn, 米粉), and cellophane noodles (fěnsī, 粉丝/粉絲). These are not made from wheat dough, but are still regarded as noodles in English due to their physical form and culinary role.
While long, thin strips may be the most common, many varieties of noodles are cut into waves, helices, tubes, strings, or shells, or folded over, or cut into other shapes. Noodles are usually cooked in boiling water, sometimes with cooking oil or salt added. They can also be steamed, pan-fried, deep-fried, or baked. Noodles are often served with an accompanying sauce or in a soup, the latter being known as noodle soup. Noodles can be refrigerated for short-term storage or dried and stored for future use.
