4. Onions and Potatoes
You’ve probably seen onions and potatoes stored together in rustic baskets, but that’s actually a storage mistake. Onions give off moisture and gases that cause potatoes to sprout and spoil faster. Potatoes also release moisture, which speeds up decay in onions. Together, they create a damp, warm environment that both hate. Onions prefer a dry, dark space with good air circulation. Potatoes need a cool, dark place but not one that’s too humid. When stored together, both break down faster than they should. Keep onions in a mesh bag or open bin away from other produce. Store potatoes in a paper bag or basket on a separate shelf in the pantry.
