Scallions are a variety of young onion also referred to as green onions and spring onions. A scallion is made up of a white base that has not fully developed into a bulb and long green stalks that resemble chives. Both the white and the green parts are used in recipes and eaten both raw and cooked.
Scallions may be cooked, either whole or chopped, but are perhaps most enjoyed fresh in salads, as crudites or as a last-minute topper for sauces.
