Scallions (also known as green onions and spring onions) are edible vegetables of various species in the genus Allium. Scallions generally have a milder taste than most onions. Their close relatives include garlic, shallots, leeks, chives,[1] and Chinese onions.[2]
Although people use the bulbs of many Allium species as food, the defining characteristic of scallion species is that they lack a fully-developed bulb. Instead the Allium species referred to as scallions provide hollow, tubular green leaves growing directly from the bulb. These leaves are used as a vegetable and can be eaten either raw or cooked. Often the leaves are chopped into various dishes and used as garnishes.[3]
The names scallion and shallot are derived from the Old French eschalotte, by way of eschaloigne, from the Latin Ascalōnia caepa or Ascalonian onion, a namesake of the ancient city of Ascalon.[4] [5] [6]
Various other names are used throughout the world to describe scallions including spring onion, green onion, table onion, salad onion, onion stick, long onion, baby onion, precious onion, wild onion, yard onion, gibbon, syboe (Scots) and shallot.
Species and cultivars that may be used as scallions include
Scallions generally take 7–14 days to germinate depending on the variety.[10]
Scallions may be cooked or used raw as a part of salads, salsas or Asian recipes. Diced scallions are used in soup, noodle and seafood dishes, sandwiches, curries and as part of a stir fry. In many Eastern sauces, the bottom half-centimetre (quarter-inch) of the root is commonly removed before use.
In Mexico and the Southwest United States, cebollitas are scallions that are sprinkled with salt, grilled whole and eaten with cheese and rice. Topped with lime juice, they are typically served as a traditional accompaniment to asado dishes.[11] [12]
In Catalan cuisine, calçot is a type of onion traditionally eaten in a calçotada (plural: calçotades). A popular gastronomic event of the same name is held between the end of winter and early spring, where calçots are grilled, dipped in salvitxada or romesco sauce, and consumed in massive quantities.[13] [14]
In Japan, tree onions (wakegi) are used mostly as topping of Japanese cuisine such as tofu. In Nepal, scallion is used in different meat dish fillings like momo and choyla (meat intertwined with scallion and spices).
In China, scallion is commonly used together with ginger and garlic to cook a wide variety of vegetables and meat. This combination is often called the "holy trinity" of Chinese cooking,[15] [16] much like the mirepoix (celery, onions, and carrots) in French cuisine or the holy trinity in Cajun cuisine. The white part of scallion is usually fried with other ingredients while the green part is usually chopped to decorate finished food.
In Vietnam, Welsh onion is important to prepare dưa hành (fermented onions) which is served for Tết, the Vietnamese New Year. A kind of sauce, mỡ hành (Welsh onion fried in oil), is used in dishes such as cơm tấm, bánh ít and cà tím nướng. Welsh onion is the main ingredient in the dish cháo hành, which is a rice porridge used to treat the common cold.
In India, it is sometimes eaten raw as an appetizer. In north India, coriander, mint and onion chutney are made using uncooked scallions. It is also used as a vegetable with Chapatis and Rotis. In south India, spring onions stir fried with coconut and shallots (known as Vengaya Thazhai Poriyal in Tamil and Ulli Thandu Upperi in Malayalam) are served as a side dish with rice.In Ireland, scallions are chopped and added to mashed potatoes, known as champ or as an added ingredient to Colcannon.
In the southern Philippines, it is ground in a mortar along with ginger and chili pepper to make a native condiment called wet palapa, which can be used to spice dishes or as a topping for fried or sun-dried food. It can also be used to make the dry version of palapa, when it is stir fried with fresh coconut shavings and wet palapa.
At the Passover meal (Seder), Afghan Jews and Persian Jews strike one another with scallions before singing "Dayenu", thus re-enacting the whipping endured by the Hebrews enslaved by the ancient Egyptians.[17] [18]
Scallion oil is sometimes made from the green leaves. The leaves are chopped and lightly cooked, then emulsified in oil that is then used as a garnish.
