Does the Wet Paper Towel Trick Stop You From Crying When Cutting Onions?

Wondering how to cut onions without crying paper towel hacks? We test the popular viral kitchen trick and share practical ways to prep onions for easy weeknight meals.

The Viral Hack: Can a Damp Towel Save Your Eyes?

If you spend any time watching food videos online, you have likely seen the trick where home cooks place a folded wet paper towel next to their cutting board. The claim is simple: the moisture in the towel attracts the sulfur compounds released by the onion before they ever reach your eyes.

While it sounds almost too easy to be true, many cooks swear by it. But does it actually work, or is it just another internet myth?

  • Place a damp paper towel right next to your cutting board
  • Keep the towel damp throughout your prep work
  • Observe if your eyes water less during chopping

The Science Behind Onion Tears

To understand why people try tricks like the damp towel, it helps to know why onions make us cry in the first place. When you slice into an onion, you rupture its cell walls, releasing enzymes and amino acid sulfoxides that mix to form a volatile gas.

When this gas hits the moisture in your eyes, it creates a mild sulfuric acid, triggering your tear glands to flush it out. Any method that intercepts or neutralizes that gas can potentially reduce the waterworks.

  • Cell walls break down during slicing
  • A volatile gas is released into the air
  • Gas mixes with eye moisture to form acid

Putting the Wet Paper Towel Trick to the Test

Does the wet paper towel method actually hold up in a real kitchen? The theory is that the airborne sulfur compounds are drawn to the moisture on the towel rather than traveling upward toward your face.

While results vary depending on the ventilation in your kitchen and the sharpness of your knife, many home cooks find it provides a modest improvement. It might not eliminate tears entirely, but it is harmless to try when you are prepping dinner.

  • Use a clean paper towel dampened with cool water
  • Set it close to the base of the onion while cutting
  • Combine with a sharp knife for best results

Other Reliable Ways to Reduce Onion Tears

If the damp towel does not completely solve your problem, you can combine it with other classic kitchen techniques. Using a very sharp chef's knife causes less cellular damage, releasing fewer gas compounds into the air.

You can also chill your onions in the refrigerator for thirty minutes before slicing, which slows down the chemical reaction that causes irritation. Once your onions are safely chopped, you are ready to tackle everything from quick weeknight sautés to hearty dinners.

  • Always use a sharp knife to slice cleanly
  • Chill onions in the fridge before cutting
  • Turn on your kitchen vent fan to clear the air
