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.
