Spring onions

Scallion, green onion, spring onion and salad onion are English names (with many other regional names throughout the world) for various Allium species. Scallions have a milder taste than most onions. Its close relatives include the garlic, shallot, leek, chive, and Chinese onion.

The bulbs of many Allium species are used as food. But the defining characteristic of scallion species is that they lack a fully developed bulb. In common with all Allium species, scallions have hollow, tubular green leaves, growing directly from the bulb. These leaves are used as a vegetable; they are eaten either raw or cooked. The leaves are often chopped into other dishes, in the manner of onions or garlic.

The words scallion and shallot are related and can be traced back to the Greek ασκολόνιον ('askolonion') as described by the Greek writer Theophrastus. This name, in turn, seems to originate from the name of the ancient Canaan city of Ashkelon. The plant itself came from farther east of Europe.

Species and cultivars which may be called "scallions" include:

Spring onions 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, as well as sandwiches, curries or as part of a stir fry. In many Eastern sauces, the bottom half-centimetre (quarter-inch) of scallions roots is commonly removed before use.

In Mexico and the Southwest United States, cebollitas are scallions that are sprinkled with salt and grilled whole and used with cheese and rice. Topped with lime juice, they typically serve as a traditional accompaniment to asado dishes.

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.
