Foods You Should Never Refrigerate

3. Onion

Storing onions in the refrigerator for too long can cause them to become soft and even develop mold. Unpeeled onions need proper airflow for long-term storage, which is why keeping them in plastic bags inside the fridge is not recommended. Instead, they should be stored in a cool, dry, and well-ventilated place. However, peeled onions are an exception—these should be kept in resealable containers inside the refrigerator to maintain freshness.
