Scallion in the context of "Udon"

The onion (Allium cepa L.Tooltip Carl Linnaeus, from Latin cepa), also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus Allium. The shallot is a botanical variety of the onion which was classified as a separate species until 2011. The onion's close relatives include garlic, scallion, leek, and chives.

The genus contains several other species variously called onions and cultivated for food, such as the Japanese bunching onion Allium fistulosum, the tree onion Allium × proliferum, and the Canada onion Allium canadense. The name wild onion is applied to a number of Allium species, but A. cepa is exclusively known from cultivation. Its ancestral wild original form is not known, although escapes from cultivation have become established in some regions. The onion is most frequently a biennial or a perennial plant, but is usually treated as an annual and harvested in its first growing season.

The shallot /ʃəˈlɒt/ is a cultivar group of the onion. Until 2010, the (French red) shallot was classified as a separate species, Allium ascalonicum. The taxon was synonymized with Allium cepa (the common onion) in 2010, as the difference was too small to justify a separate species.

As part of the onion genus Allium, its close relatives include garlic, scallions, leeks, chives, and the Chinese onion.

A leek is a biennial vegetable, a cultivar of Allium ampeloprasum, the broadleaf wild leek (syn. Allium porrum). The edible part of the plant is a bundle of leaf sheaths that is sometimes colloquially called a "stem" or "stalk".

The genus Allium also contains the onion, garlic, shallot, scallion, chives, and Chinese onion. Three closely related vegetables—elephant garlic, kurrat and Persian leek or tareh—are also cultivars of A. ampeloprasum, although different in their culinary uses.

Hilling, earthing up or ridging is the technique in agriculture and horticulture of heaping soil up around the base of a plant. It can be done by hand (usually using a hoe), or with powered machinery, typically a tractor attachment.

Hilling buries the normally above-ground part of the plant, promoting desired growth. This may encourage the development of additional tubers (as with potatoes), force the plant to grow longer stems (leeks), or for some crops (chicory, leeks, asparagus etc.) this blanching technique keeps the stems or shoots pale and tender, or influences their taste.

Allium is a large genus of monocotyledonous flowering plants with around 1000 accepted species, making Allium the largest genus in the family Amaryllidaceae and among the largest plant genera in the world. Many of the species are edible, and some have a long history of cultivation and human consumption as a vegetable including the onion, garlic, scallions, shallots, leeks, and chives.

Allium species occur in temperate climates of the Northern Hemisphere, except for a few species occurring in Chile (such as A. juncifolium), Brazil (A. sellovianum), and tropical Africa (A. spathaceum). They vary in height between 5–150 centimetres (2–59 in). The flowers form an umbel at the top of a leafless stalk. The bulbs vary in size between species, from small (around 2–3 mm in diameter) to rather large (8–10 cm). Some species (such as Welsh onion A. fistulosum and leeks (A. ampeloprasum)) develop thickened leaf-bases rather than forming bulbs as such.

Allium fistulosum, the Welsh onion, also commonly called bunching onion, long green onion, Japanese bunching onion, and spring onion, is a species of perennial plant, often considered to be a kind of scallion.

The species is very similar in taste and odor to the related common onion, Allium cepa, and hybrids between the two (tree onions) exist. A. fistulosum, however, does not develop bulbs, and its leaves and scapes are hollow (fistulosum means 'hollow'). Larger varieties of A. fistulosum, such as the Japanese negi, resemble the leek, and smaller varieties resemble chives. A. fistulosum can multiply by forming perennial evergreen clumps. It is also grown in a bunch as an ornamental plant.

Allium chinense (also known as Chinese onion, Chinese scallion, glittering chive, Japanese scallion, Kiangsi scallion, and Oriental onion) is an edible species of Allium, native to China, and cultivated in many other countries. Its close relatives include the onion, scallion, leek, chive, and garlic.

Sham Ennessim (Arabic: شم النسيم, Sham Al Nassim or Sham an-Nassim; Egyptian Arabic: Sham Ennesim, IPA: [ˈʃæmm ennɪˈsiːm]) is a festival marking the beginning of spring, celebrated by Egyptians of all religions. It is an official public holiday in Egypt. Sham Ennessim always falls on Easter Monday, which is the day after Easter, in accordance with the Coptic Orthodox Church. The Arabic name Sham Ennesim translates into "Smelling/Taking In the Zephyrs".

The festival is characterized by a number of traditional practices. Egyptians typically spend the entire day outdoors, engaging in picnics in public gardens, green spaces, along the Nile, or at the zoo. The customary foods consumed on this occasion include fesikh, a fermented, salted, and dried grey mullet, along with lettuce, green onions, and lupin beans. A widespread tradition associated with the festival is the coloring of boiled eggs, which are subsequently eaten or exchanged as gifts.

Ramen (/ˈrɑːmən/) (拉麺, ラーメン or らあめん, rāmen; [ɾaꜜːmeɴ] ) is a Japanese noodle dish. It is a part of Japanese Chinese cuisine. It includes Chinese-style alkaline wheat noodles (中華麺, chūkamen) served in several flavors of hot broth. Common flavors are soy sauce and miso, with typical toppings including sliced pork (chāshū), nori (dried seaweed), lacto-fermented bamboo shoots (menma), naruto, and scallions. Nearly every region in Japan has its own variation of ramen, such as the tonkotsu (pork bone broth) ramen of Kyushu and the miso ramen of Hokkaido.

The origins of ramen can be traced back to Yokohama Chinatown in the late 19th century. While the word "ramen" is a Japanese borrowing of the Chinese word lāmiàn (拉麵), meaning "pulled noodles", the ramen does not actually derive from any lamian dishes. Lamian is a part of northern Chinese cuisine, whereas the ramen evolved from southern Chinese noodle dishes from regions such as Guangdong, reflecting the demographics of Chinese immigrants in Yokohama. Ramen was largely confined to the Chinese community in Japan and was never popular nationwide until after World War II (specifically the Second Sino-Japanese War), following increased wheat consumption due to rice shortages and the return of millions of Japanese colonial settlers from China. In 1958, instant noodles were invented by Momofuku Ando, further popularizing the dish.
