No crying onion cutting
The no cry onion solution.
Some may tell you:
-cut under water or running water (moderate success, but you get wet onions)
-whistle (it blows away the chemicals, weak success)
But the no fail solution is…
… to wear goggles
Serious. It works every time. Even if your DB thinks you are a plonker.
I have sensitive eyes and I can cut onions like a demon when I wear my swimming googles. The smarting chemicals can’t reach your eyes.
Science note: it is a complex sulphur molecule that breaks down into hydrogen sulphide, sulphur dioxide and sulphuric acid. Prechilling the onion will also lessen the effect as the enzyme which starts breaking down the sulphur compound is relatively inactive at low temps.
