4. Use as Mini Containers for Freezing
Clean tuna cans also work well for freezing small food portions. You can freeze soup stock, sauce cubes, lemon juice, or baby food in them.
Tip: Don’t fill the cans to the top – leave a bit of space because liquids expand when frozen. Once frozen, you can transfer the contents into bags or containers for long-term storage.
5. Label for Easy Identification
Since all tuna cans look the same once cleaned, labeling is key. Use masking tape or stickers to write the food name and date.
This helps you check how long something has been in the fridge and makes sure you use older items first – preventing waste and spoilage.
6. Important Safety Notes
While tuna cans are practical, avoid using them for acidic foods like tomato sauce or citrus, as the metal can react and affect flavor.
Also, don’t reuse cans with sharp edges or rust spots. For longer storage, transfer the contents into glass jars or airtight containers after chilling.
Conclusion
Reusing tuna cans is a simple and sustainable way to make the most of what you already have. With proper cleaning and smart organization, these small containers can become perfect tools for food storage in your refrigerator.
