The best potato storage containers are breathable, opaque bins or baskets (like wicker, vented plastic, or even a DIY-holed cardboard box) placed in a cool, dark, dry spot, away from onions, to prevent sprouting and spoilage by allowing air circulation and blocking light. Popular choices include wooden boxes with mesh screens, metal bins, or even milk crates, with newspaper lining often recommended for moisture absorption.
