Every home cook knows the dreaded sting of onion fumes, but a simple kitchen trick circulating on social media promises to keep those tears at bay. A food enthusiast on TikTok has demonstrated a surprisingly effective method that involves nothing more than a cup and some hot water.
The Viral Hack: A Minute in Hot Water
TikTok user @yoshiandfrndz shared a video that has captured the attention of frustrated chefs everywhere. The technique is straightforward: place a whole onion in a cup, pour hot water over it, and let it sit for approximately one minute. Once the water changes colour, pour it away and proceed to chop. The user claims this results in "no more teary eyes while cutting."
The post sparked a lively discussion in the comments, with viewers offering their own tried-and-tested solutions. One person humourously noted their spouse delegates the task, while others suggested practical alternatives like chilling onions overnight or investing in a pair of specialised onion goggles.
The Science Behind the Sting
Why do onions make us cry in the first place? The Atlantic Eye Institute has clarified the chemistry, pinpointing a key compound called suberin. This substance, found in cork tissue plants, helps repair damage and protect against moisture loss.
"When you cut into an onion, you release this chemical and other enzymes," the Institute explains. "The reaction that occurs creates sulphuric acid; when the fumes come into contact with the moisture in your eyes, you feel a burning sensation." The root of the onion contains a high concentration of suberin, which is why cutting methods matter.
Expert-Approved Strategies for Tear-Free Chopping
Beyond the hot water method, experts endorse several other approaches to minimise the eye-watering effect. Keeping the root intact as long as possible is highly recommended, as it limits the release of the irritating compounds. Peeling and cutting from the bloom (top) end first is advised.
Another crucial tip is to use a sharp knife. A dull blade crushes and tears the onion cells, releasing more fumes, whereas a sharp knife makes cleaner cuts and reduces prep time, thereby limiting exposure.
In summary, whether you try the viral one-minute hot water soak, chill your onions, sharpen your knife, or master the root-end technique, a tear-free chopping experience is well within reach.
