Which technique helps minimize tears when cutting onions?

• A. Chill the onion before cutting
• B. Cut in warm environment
• C. Peel before chilling
• D. Cut near fans to blow fumes away

Answer: (A)

Tearing up when chopping onions happens because cutting them releases a sulfuric gas that irritates the eyes. Chilling the onion before cutting slows the chemical reactions that produce that gas and makes it less volatile, so fewer fumes reach your eyes. This cooling step directly reduces how much irritant is formed and escapes, making it the most reliable way to minimize tears. Cutting in a warm environment would encourage more gas release, not less. Peeling before chilling doesn’t change the amount of irritant produced, and cutting near a fan only helps disperse fumes rather than reduce their formation. So, chilling the onion before cutting is the best approach.
