There are a few tricks that will help you to keep food fresher so that it lasts longer. If you have ever bought lettuce and thrown half of it away because it turned brown a few days later or found that your onions simply did not last long enough for you to use them all, you may need to learn a few of these tips.
Freeze Green Onions in Plastic
If you drink bottled water or even sodas in plastic bottles, save a few of them for storing green onions. Just cut the onions up and make sure that they are completely dry so that they do not get freeze burn. Pour them into the plastic bottle, date it and then freeze. This is a great space-saving way to keep green onions around for a while and when you need them, you just have to pour out the amount that you need and stick the rest back in the freezer.
