Tip! How to Cut an Onion Without Crying

I’ve seen a lot of tips “claiming” they can teach me how to cut an onion without crying.

And while some of them dampened the tears, they didn’t get rid of them.

If you’re like me, you cry unabashedly when you cut an onion.

Seriously… it’s like someone’s turned on the water in my eyes.

Sometimes, I’m actually afraid that I’ll cut myself it becomes to hard to see. And don’t get me started on how much my eyes burn!

How to Cut an Onion Without Crying

When I came across a post from Miss Information claiming a candle can make all the difference, I kind of rolled my eyes… but I thought to myself, “What do I have to lose?”

Was this going to a #PinFail or a #PinWin?

What does the post say? Burn a candle near your cutting area and your eyes won’t burn.

Would this work?

Pin Win: Cutting Onions. No Crying!

I put the idea to the test while I was making my famous Jenny Burgers.

If you haven’t my famous Jenny Burgers, it’s a crying shame. (Sorry… couldn’t resist the pun!) Try my In-demand Jenny Burgers this weekend!

I grabbed our kitchen candle, lit that sucker up and began cutting away.

One whole onion later and I had absolutely no tears and no eye burning. It actually worked! But how?

Apparently, when we cut an onion, the onion releases a gas.

That gas gets mixed in with some of the enzymes from the onion, creating sulfur gas.

And how does your eyes protect themselves? Well, they create tears of course!

It seems the candle burns the gas so it doesn’t get to our eyes.

The trick is to keep the candle close.

(A special thanks to Science Bob for explaining why we cry when we cut an onion. )
