Slice onions without tearing up
Onions are some of the best-tasting vegetables on the planet. The kind of onion doesn’t matter. If it’s an onion, it’s going to taste good on anything. The only bad thing about onions is that they can cause you to bawl your eyes out for absolutely no reason.
To avoid tearing up while slicing onions, stick your onions in the freezer an hour beforehand. The gas irritant will freeze and adhere to the onion’s flesh, limiting how high it wafts into the air. This trick works with any kind of onions, including garlic and green onions.
