UK households throw away around 170,000 onions a day, as everyday storage habits leave onions and garlic rotting long before they should. An ordinary brown paper bag might be the difference between crisp, flavour-packed onions and garlic and a slimy mess at the back of the cupboard. After trying it, she found her garlic and onions were still "fresh and firm" after three months in a paper bag. Stored in a cool, dry cupboard like this, onions and garlic can stay usable for many months instead of a few weeks. A perforated paper bag simply makes it easier to create those conditions in an ordinary kitchen cupboard.
