After taking the onion skin off, she makes multiple slices the whole way around the onion from the root to the stem with each cut meeting in the center.

Melanie then turns the onion on its side and makes a series of thin vertical cuts starting at the stem and making her way up to the root.

‘I was today years-old when I learned that I could dice an onion like this. Please tell me that I’m not the only one,’ she said in an Instagram video.

‘I like chopping onions like this. It saves my eyes from tearing up,’ said a third.

‘Cut it in half first so you have it firmly on a flat surface will make it safer to do, you may cut yourself doing it whole,’ a fourth recommended.

Why do onions make you cry?

Onions contain a chemical compound and an enzyme that mix to release an irritating gas when the onion is cut.

This helps keep the bulb from getting eaten by animals as it grows in the ground.

Onions make your eyes burn for the same reason they make you cry: thanks to the combination of that chemical compound and the enzyme that synthesizes when an onion is cut.

This creates syn-propanethial-S-oxide, a volatile gas that makes your eyes burn and fill with tears.

Here’s how the process works:

  1. The onion contains both the chemical precursor to the gas and an activating enzyme that floats in onion cells in little walled-off areas (vacuoles).
  2. An onion gets sliced, diced or bitten into.
  3. The precursor and enzyme mix, creating an unstable chemical irritant.
  4. At room temperature, this irritant quickly becomes a gas that spreads through the air.
  5. The gas triggers pain receptors in the eyes and nose designed to protect you from chemicals, smoke and other dangers.
  6. The tear glands (lacrimal glands) in the eyes then make tears to wash away the irritant.
