About Sweet onion

Sweet onion is a mild-flavoured onion type, generally with a round bulb, papery outer skin, and layered, crisp flesh. Its raw flavour is less pungent than that of many storage onions, with a gentle sweetness that becomes more pronounced when cooked.

It is used raw in salads and sandwiches or cooked in a range of dishes. Fresh whole bulbs and cut or cooked onion are common forms; sweetness, pungency, and keeping quality vary by cultivar, growing conditions, and storage.
