Definition of scallion

The origin of the word "scallion" can be traced back to the Old English word "scalan," which meant "onion." This word referred to the small, young onions that were cultivated during medieval times. As the scallions grew, the outer layers would form a protective covering around the bulb, resembling the shells of scallops (hence the name "scallops" for a different seafood). Because of this resemblance, the name "scallions" came to describe these young onions as well. The use of "scallions" to describe these young onions became more common in the 19th century as immigration from the British Isles increased. Today, scallions are commonly used in a variety of cuisines around the world, including as a garnish for soups and stews, as an ingredient in salads and stir-frys, and as a flavorful addition to sandwiches and wraps. Despite the popularity of scallions, some people mistakenly believe that it is a distinct vegetable. However, scallions are simply young onions, harvested before they have fully formed bulbs, and are therefore a type of onion rather than a separate vegetable.
