Spring onion, also known as green onion or scallion, is a young onion harvested before it fully matures. It features a slender, elongated green stem with a small white bulb at the base. Spring onions offer a mild onion flavor and a crisp texture, making them versatile for various culinary uses. They are commonly used as both a garnish and a flavoring agent in salads, soups, stir-fries, and other dishes. Spring onions can be enjoyed raw for a fresh onion taste or cooked briefly to soften their texture.
