You can easily reduce the tearing effect, or even get rid of “onion cry” altogether with a few life hacks.
Why do we cry when slicing onions?
Of course, not because we bitterly regret his fate. It’s all about the chemical properties of this vegetable: the bulbs grow underground, and so that they are not gnawed by field mice, it has a special protective mechanism. If the onion peel is damaged, the substance lacrimator is released (Latin lacrima – tear). When it comes into contact with the liquid that coats the eyeballs, this substance turns into sulfuric acid, immediately causing tears, which wash away the irritant. In a word, the onion protects itself from us, and our body – from it. Since the tearing effect is caused by a chemical reaction, other unpleasant symptoms may appear:
- short-term runny nose;
- itching, tingling;
The most popular culinary onion varieties contain the highest amount of sulfur-containing compounds: yellow, white and red. Sweet varieties such as green onions, leeks and shallots are much less tear-resistant. Genetic scientists created a special kind of onion that doesn’t make us cry, but so far this wonderful vegetable is not available in Russia.
How to stop crying?
If you use the most teary onion varieties, then most likely, unpleasant symptoms will not be completely avoided. However, you can minimize this effect by following a few simple rules:
- Choose only fresh onions. The longer it is stored, the more intense its “combustible” effect;
- Try not to cut the onion near the root, it is there that the greatest concentration of sulfur compounds accumulates;
- Use a well-sharpened knife. The sharper it is, the less it damages the onion, which reduces the amount of emitted irritants;
- You can reduce the lacrimator content of the onion itself with water. Before slicing, simply place the onions in a bowl of ice water for half an hour;
- Turning on a cooker hood or ventilation and wearing glasses will help protect your eyes from the tear agent.
There is also a popular recipe: while cutting onions, keep a piece of white bread in your mouth, which supposedly absorbs sulfur compounds. There is no scientific evidence for this effect, but why not try it? It’s at least safe.

- Rinse your eyes thoroughly with cool water, preferably running;
- Put a cold compress on your eyes, cucumber slices will also do;
