Cutting Onions Without Tears: Tips and Tricks

Onions are a popular vegetable that is commonly used in households and professional kitchens worldwide. They add a unique flavor and aroma to various dishes, but their biggest challenge is their ability to make us cry. This is due to the release of syn-propanethial-S-oxide, an irritant chemical, when onions are cut. However, there are several effective ways to cut onions without tears.

1. Use a Sharp Knife

Using a sharp knife is one of the easiest ways to avoid crying when cutting onions. A dull knife crushes the onion cells, which leads to the release of more tear-inducing chemicals. A sharp knife creates a clean cut, which minimizes the number of cells that are damaged, significantly reducing the irritants in the air.

2. Chill the Onion

Another effective way to cut onions without tears is to chill them before cutting. Put the onion in the refrigerator for 30 minutes or the freezer for 10 minutes before you cut it. The low temperature makes the cells in the onion less volatile, reducing the release of irritants and making you less likely to cry.

3. Cut the Onion Under Running Water

The chemical irritants from onions are released into the air when you cut them, which then come in contact with your eyes. To prevent this, try cutting the onion under running water. This method binds the irritants with the water instead of the air, reducing the amount that gets into your eyes and making it an effective way to cut onions without tears.

4. Cut the Onion in Half First

Cutting the onion in half before continuing to chop it can help reduce tears. The chemical syn-propanethial-S-oxide is only released when you start cutting the onion. By starting with the onion in half, you expose fewer cells to the air, releasing fewer irritants. This method is highly effective and you can then continue to cut the onion into smaller pieces without tearing up.

5. Light a Candle

You may find it strange, but lighting a candle while cutting onions can help reduce tears. The heat from the candle draws the irritants away from the eyes and towards the flame. Place the candle on the counter next to where you are cutting the onions and make sure it is at a safe distance to prevent a fire. This method is surprisingly effective and can help you cut onions without tears.

6. Use an Onion Chopper

Using an onion chopper is another effective way to cut onions without tears. Choppers slice the onion into small pieces, minimizing the exposure of the onion cells to the air and reducing the release of irritants. They are available in manual or electric models, and are found at most kitchen supply stores. This method is also very effective if you need to chop a large amount of onions quickly.

7. Wear Protective Eyewear

It may seem obvious, but wearing protective eyewear can help prevent tearing when cutting onions. Protective eyewear, such as goggles or swimming goggles, provides a physical barrier between the irritants and the eyes, reducing the amount that gets in and causing tears. This is a good option if you have sensitive eyes or need to cut onions frequently.

Conclusion

Cutting onions without tears is essential to enjoy this versatile ingredient without any discomfort. Using any of these tips, including using a sharp knife, chilling the onion, cutting under water, cutting in half, lighting a candle, using an onion chopper, and wearing protective eyewear, will minimize the amount of irritants released and the likelihood of tears. Experiment with these methods to find the most effective one for you, and enjoy cooking delicious, tear-free dishes!
