Onions are kind of a superfood in the kitchen – they’re usually cheap to get a hold, are rich in antioxidants, and are used in tons of recipes. But onions have a lot of other uses apart from cooking with them. Take a look at some ideas from care2:
Soothe a Sore Throat:
Here’s another sore throat remedy for you. Boil about a cup of water with the peels of half an onion. Once boiling, remove the onion and serve for relief.
Ease the Pain of Burns: if you’ve sustained a mild burn, just rub some onion onto it to soothe the pain.
Have a splinter that just won’t budge? Try taping (yes, with tape, or an adhesive bandage) a piece of raw onion to it. Hold tight for about an hour before removing the onion.
Polish Metal: slice up an onion, then crush it. Combine the crushed onion with some water and use a cloth to dab this on the metal surface. Rub the metal until it’s clean.
Make Burned Rice Edible Again: accidentally let your rice burn? You don’t have to throw it away. Just place a half an onion on top of the rice to absorb the burned taste.
Prevent your avocados from browning by storing them in a plastic airtight container with red onions. Place half of an onion in the container first, skin side up, and then place the avocado. You can use red onion to store guacamole, too: Place some slices on top of the guac’ in a plastic container.
