In the high-humidity crisper drawers of the Sub-Zero 632 refrigerator, you should store fruits and vegetables that require higher moisture levels to stay fresh. These drawers are designed to maintain a higher humidity level, which helps prevent the wilting and drying out of produce. Ideal items to store in these drawers include leafy greens, cucumbers, broccoli, carrots, and other fruits and vegetables with high water content. The increased humidity helps to extend the shelf life of these items, preserving their texture and nutrients for a longer period. For best results, keep the drawers organized and avoid overcrowding, allowing proper air circulation to maintain optimal freshness.
