How to Chop onions without crying — the 3-Step Fix
Small problem, real delay — and a fix measured in minutes. Here is the fastest reliable way to chop onions without crying.
The fast method
- Chill the onion 15 minutes in the freezer first — cold slows the tear gas.
- Use your sharpest knife: clean cuts rupture fewer cells.
- Breathe through your mouth and lean back; or run the vent hood on high right above the board.
Why it works
Cutting releases enzymes that form syn-propanethial-S-oxide — the volatile compound that airborne-attacks your eyes. Cold and sharpness both reduce how much launches.
Worth knowing
A dull knife is a tear-gas machine — this tip is secretly about sharpening.
