Ever wondered why onions make us cry? Here’s the science behind the sniffles 👇
When you cut into an onion, it releases sulfenic acid, which quickly turns into a gas called syn-Propanethial-S-oxide.
That gas wafts up to your eyes, reacts with your tears, and forms a mild sulfuric acid — cue the sting and the waterworks! 😭💧
✨ A few tear-free chopping tricks:
🔪 Chill your onions before cutting
💨 Slice near running water or under an extractor fan
🕶️ Wear goggles (yes, seriously — chef chic!)
So next time you’re in the kitchen with watery eyes, remember — it’s not you, it’s the onion. 😉
