About White onion

White onion is an onion variety with papery white skin and white flesh. Its crisp layers have a pungent, sharp flavour when raw, which becomes sweeter and softer with cooking; intensity varies with growing conditions and storage.

It is used raw in salads, salsas and garnishes, or cooked in soups, sauces and other savoury foods. White onions are often sold whole, and their flavour and moisture can differ from yellow or red onions; peeled or chopped products may also be available.
