@chefsblackboard: Ever cried while cutting onions? 😅 It’s not emotion — it’s science! When we chop onions, they release a gas called syn-propanethial-S-oxide that burns our eyes and makes us tear up. Chill your onions before cutting ❄️ — fewer tears, happy cooking! 👨🍳✨ #CulinaryScience #OnionFacts #ChefLife #CookingTips #KitchenSecrets
