Store peeled onions in an airtight container or a resealable plastic bag in the refrigerator to prevent the smell from spreading. Ensure the container or bag is properly sealed.
Peeled onions release volatile sulfur compounds that are responsible for their pungent odor. These compounds can easily permeate other foods in your refrigerator, affecting their taste and smell. To prevent this, you need to create a barrier that traps these compounds.
Here's a step-by-step guide:
Choose a suitable container: Select an airtight container made of glass or plastic. A container with a rubber gasket seal is ideal.
Alternatively, use a resealable bag: If you don't have an airtight container, a heavy-duty resealable plastic bag will work. Ensure it's free of holes.
Place the onion inside: Put the peeled onion halves or pieces into the container or bag.
Seal tightly: Ensure the container lid is securely fastened or the resealable bag is completely sealed. Press out any excess air from the bag before sealing.
Refrigerate immediately: Place the sealed container or bag in the refrigerator. The cold temperature will help slow down the release of the sulfur compounds.
Following these steps will significantly reduce the onion smell in your refrigerator and help keep your other foods fresh.
To further minimize odor, wrap the peeled onion in plastic wrap before placing it in the airtight container or bag. This adds an extra layer of protection against smell leakage.
