Noodle soup in the context of "Soba"

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.

Chili oil or chile oil is a condiment made from vegetable oil that has been infused with chili peppers. Different types of oil and hot peppers are used, and other components may also be included. It is commonly used in Chinese cuisine, Mexico, Italy, and elsewhere. It is particularly popular in Chinese cuisine, especially western Chinese cuisines, such as Sichuan cuisine, Hunan cuisine, Guizhou cuisine, and Shaanxi cuisine, where it is used as an ingredient in cooked dishes, as well as as a condiment. It is sometimes used as a dip for meat and dim sum. It is also employed in the Korean Chinese noodle soup dish jjamppong. A closely related condiment in Chinese cuisine is chili crisp, which contains edible chunks of food and chilis in oil.

Chili oil is typically red in color. It is made from vegetable oil, often soybean oil or sesame oil, although olive oil or other oils may be used. Other spices may be included, such as Sichuan pepper, garlic, or paprika. Commercial preparations may include other kinds of oil, water, dried garlic, soy sauce, and sugar. Recipes targeted to Western cooks also suggest other popular oils, such as rapeseed, grapeseed or peanut, and any dried or fresh chili peppers. The solids typically settle to the bottom of the container in which it is stored. When using chili oil, the cook or diner may choose how much of the solids to use; sometimes only the oil is used, without any solids.
