Why do onions make us cry?
Onions contain a chemical called syn-propanethial-S-oxide. When you cut into an onion, enzymes react with this compound, resulting in the release of a gas. When this gas reaches our eyes, it mixes with our tears and forms a mild sulfuric acid. As a defense mechanism, our eyes produce more tears to dilute and wash away the irritant.
What can I do to prevent tearing up while chopping onions?
Luckily, there are several methods you can try to minimize onion-induced tears:
- Chill the onion: By refrigerating the onion for around 30 minutes before chopping, you can reduce the release of the irritating gas.
- Use a sharp knife: When you use a sharp knife, you create cleaner cuts, reducing the amount of gas released.
- Work near running water: Positioning your cutting board next to a running faucet can help direct the gas away from your eyes.
- Wear goggles: Wearing goggles or even swimming goggles can create a barrier between the gas and your eyes, preventing tears.
- Light a candle: Lighting a candle near your cutting board can help burn off the gas before it reaches your eyes.
What other tips can help me chop onions without crying?
Aside from the methods mentioned above, you can try these additional strategies:
- Cut under running water: Submerging the onion or cutting it under running water can prevent the gas from reaching your eyes.
- Use a kitchen fan: Directing the fumes away from your face using a kitchen fan can be helpful in reducing tears.
- Wear contact lenses: Contact lenses act as a barrier, preventing the gas from reaching your eyes.
Are there any specific onion varieties that cause fewer tears?
Yes, certain types of onions produce fewer tears due to their lower sulfur content. You can try using sweet onions, such as Vidalia or Walla Walla, as they are known to be less tear-inducing.
What should I do if I still tear up while chopping onions?
If you find yourself tearing up despite following all these techniques, don’t worry! Some people are more sensitive to onion fumes than others. You can try using a food processor with an onion attachment or purchase pre-chopped onions from the grocery store to avoid the tears altogether.
Remember, practice makes perfect! With time, you’ll develop your own methods to chop onions without shedding tears. Happy tear-free chopping!
