How to Stop Tears When Cutting Onions

Onions are a staple in many recipes, but cutting them can be a real tearjerker for many people. The sulfenic acid released when onions are chopped can trigger an inflammatory response in the eyes, leading to watery eyes and tears. However, there are several effective methods to help you cut onions without shedding a tear. Here are some tips to stop tears when cutting onions.

1. Chill the Onions

One of the most common ways to stop tears when cutting onions is to chill them. Place the onions in the refrigerator for about 30 minutes before cutting. The cold temperature helps to slow down the sulfenic acid release, reducing the inflammation in your eyes.

2. Use a Sharp Knife

A dull knife can cause more irritation and tears when cutting onions. Use a sharp, clean knife to chop the onions quickly and efficiently. A sharp blade reduces the friction and pressure on the onions, which can minimize the release of sulfenic acid.

3. Cut Onions Under Cold Water

Another effective method is to cut onions under cold running water. This helps to dilute the sulfenic acid and reduce the inflammation in your eyes. As you cut the onions, the water can also wash away any released acid, further minimizing tear production.

4. Wear Safety Glasses

For those who still experience severe tearing, wearing safety glasses can be a lifesaver. These glasses are designed to protect your eyes from any potential irritants, including the sulfenic acid released when cutting onions. While they may not completely stop tears, they can provide some relief.

5. Use a Microplane Grater

If you need to finely chop onions, consider using a microplane grater instead of a knife. The fine teeth of the grater can cut onions quickly and efficiently without causing as much irritation as a knife.

6. Keep Your Face Turned Away

When cutting onions, try to keep your face turned away from the cutting board. This can help to minimize the amount of sulfenic acid that comes into contact with your eyes.

7. Breathe Through Your Nose

Breathing through your nose can help to prevent the sulfenic acid from reaching your eyes. When you inhale through your mouth, the gas can travel up to your eyes, triggering tears. So, take a deep breath and try to keep your mouth closed while cutting onions.

In conclusion, cutting onions doesn’t have to be a tearful experience. By following these tips, you can reduce the inflammation in your eyes and stop tears when cutting onions. Happy cooking!
