How to Cut Onions Without Crying?
Chopping onions is a necessary job in the kitchen—it's the key to so many recipes, like all kinds of casseroles, salads, and party dips. But the task can often leave your eyes so irritated that by the end of prep you're basically sobbing. Have no fear and have no tears: Read on to find out how to cut onions without crying.
切洋葱是厨房中一项必不可少的工作——它是许多食谱的关键，比如各种砂锅菜、沙拉和聚会蘸酱。但这项任务常常会让你的眼睛非常难受，以至于在准备工作结束时，你基本上都在哭泣了。别害怕，也别流泪：继续读下去，了解如何切洋葱时不流泪。
Why do onions make you cry?
为什么洋葱会让你流泪？
First things first—why do onions make you cry? There's a bit of science behind it: Long story short, onions emit a compound when sliced that gets into the air and can irritate the nerves around the eyes, making you start to tear up. It's unavoidable to a certain extent—but there are some things you can do to lessen the burn and prevent a total cry-fest.
首先，为什么洋葱会让你流泪呢？这背后有一些科学道理：长话短说，洋葱在被切开时会释放出一种化合物，这种化合物会进入空气中，并刺激眼睛周围的神经，让你开始流泪。在一定程度上这是不可避免的——但你可以采取一些措施来减轻刺痛感，并避免完全泪流满面。
How do I stop my eyes from watering when cutting onions?
我怎样才能在切洋葱时不让眼睛流泪呢？
For starters, make sure you're using a sharp knife. The sharper your knife, the less likely you are to cry when you chop an onion. A dull knife will actually smash the onion rather than slice it cleanly, so the onion lets out more of the compound that irritates the eyes. Use a good chef's knife and break out your knife sharpener regularly to sharpen it up.
首先，确保你使用的是一把锋利的刀。你的刀越锋利，切洋葱时你流泪的可能性就越小。一把钝刀实际上会把洋葱压碎，而不是干净利落地切开，所以洋葱会释放出更多刺激眼睛的化合物。使用一把好的厨师刀，并定期拿出你的磨刀器来磨快它。
Another simple and pretty effective trick: Freeze the onion for about 10 or 15 minutes before you cut it. The blast of cold prevents the tear-causing enzyme from releasing into the air. If you go this route, just be sure to slice quickly once you remove the onion from the freezer—as it warms up, the enzyme will become more active and begin to irritate your eyes again. Another trick is to store your chopped onions in a bowl of very cold water as you chop—this will halt the compound from getting into the air.
另一个简单且相当有效的技巧：在切洋葱之前，将洋葱冷冻大约10到15分钟。寒冷的冲击会阻止导致流泪的酶释放到空气中。如果你选择这种方法，一定要在从冰箱里取出洋葱后迅速切开——因为随着洋葱变暖，这种酶会变得更加活跃，并再次开始刺激你的眼睛。另一个技巧是在你切洋葱时，将切好的洋葱放在一碗非常冷的水中——这将阻止这种化合物进入空气中。
The last and most effective strategy for not bursting into tears when you cut an onion is to protect your eyes! If you have contact lenses then you're already ahead of the game—they are a good barrier that will lessen the irritation. Regular glasses will help too, but not much. Try purchasing a pair of kitchen goggles: They may not be a fashion statement, but they seal around your eyes so none of the tear-inducing compound can get by. (Ski, swim, or safety goggles would work here too!)
最后也是最有效的切洋葱时不流泪的策略是保护你的眼睛！如果你戴隐形眼镜，那么你已经占了先机——它们是很好的屏障，可以减轻刺激。普通眼镜也会有帮助，但效果不是很大。试着买一副厨房护目镜：它们可能不是时尚的象征，但它们可以在你眼睛周围密封，这样就不会有任何导致流泪的化合物能够进入。（滑雪护目镜、游泳护目镜或安全护目镜在这里也同样适用！）
Whatever you choose to do, just don't give up on onions! There are so many types of onions that add so much flavor to so many recipes that they're worth a few tears!
无论你选择怎么做，都不要放弃洋葱！有这么多种类的洋葱，它们能为这么多食谱增添如此多的风味，所以它们值得你流几滴眼泪！
