How To Select White Onions
White onions will have a thin and papery white skin. Choose white onions that are heavy for their size, firm, and free from bruises.
How To Store White Onions
Store whole white onions in a cool, dry, dark place with the skin on. White onions need ventilation to stay fresh, so do not store whole onions in a plastic bag. Pre-cut white onions can be stored in an air-tight container in the refrigerator.
