Why do onions make you cry?
Onions contain a volatile compound called syn-propanethial-S-oxide, which is released when the onion is cut. When this compound comes into contact with your eyes, it forms sulfuric acid, which can cause a burning sensation and make your eyes tear up. To reduce the amount of syn-propanethial-S-oxide released, you can try chilling the onion in the fridge or freezer before cutting it, or cutting the onion under running water. You can also wear protective eyewear or cut the onion near an open flame, like a gas stove, which can burn off the compound before it reaches your eyes.
Onions are the perfect base for many recipes, adding a depth of flavor and aroma that is unmatched by any other ingredient.
