Although onions taste delicious, watering eyes come with the process when you cut them up. Thankfully, Good Housekeeping has suggested some tips to prevent yourself from crying while you are trying to cut up an onion.
According to the findings from the Institute, putting onions in a fridge 30 minutes before cutting can prevent the annoying hurt, as the cold stops tear-jerking (催泪的) gas from being produced.
Another way to reduce the gas released by the onion is to put it in water for a while. Good Housekeeping recommends: "Cut the end off the onion and then put it straight into a bowl of water. The water will draw out the acid making your tears fewer when you cut it."
When an onion grows, it mixes with sulfur (硫) in the soil to create a special mineral acid. When the onion is cut into pieces, it reacts and creates a gas. As it reaches your face, this annoying gas causes the eyes to produce tears.
The root is where the gases are most concentrated, so it is recommended that this part of the onion be left on as you cut it to avoid uncomfortable eyes. Do this by cutting the vegetable in half down the middle, then cut off part of one side to create a flat surface. Then, place the onion with its flat surface down and cut it towards the root.
Also, to reduce the gas's effect on your eyes, cut it next to a window or near a fan so the gas is blown away from your face. And take care to use a sharp knife; this will make it easier to move through the vegetable, causing fewer cells to be broken and less gas to be released as a result.
