Scientific Study Debunks Onion Myths: Sharpness, Not Temperature, is Key to Tear-Free Chopping

The ubiquitous onion, an essential ingredient in countless cuisines across the globe, brings with it a singular, tear-jerking paradox. For centuries, the act of preparing this fragrant bulb has been synonymous with a cascade of involuntary tears, a seemingly unavoidable toll paid for flavor. This shared culinary struggle has spurred an array of home remedies, from the bizarre to the marginally plausible, yet none have offered a universally reliable solution. It is this frustrating dilemma that spurred modern scientific inquiry, culminating in a definitive, evidence-based answer to the age-old question of how to slice, dice, and chop without weeping, finally moving beyond anecdotal advice to reveal the true mechanism behind the watery ordeal.
