To maintain their freshness, Chinese onions should be stored in a cool, dry place. If you have purchased them fresh, it’s best to store them in the refrigerator in a crisper drawer. Wrapping them in a damp paper towel inside a plastic bag can help retain moisture without causing them to rot.
If you have leftover chopped Chinese onions, store them in an airtight container in the refrigerator and use them within a few days to ensure optimal flavor and quality. Avoid washing them until you’re ready to use them, as moisture can promote spoilage. Proper storage is key to enjoying their delicious flavor for as long as possible.
