I love onions. I love the look of them, the way they smell when you cook them, and the way they taste. There is one thing about onions I don't like, though. I'm sure that a lot of people will agree with me on this one. I hate the way onions make you tear up when they are cut.But I heard a great report on All Things Considered the other day about an onion that won't make you cry. The reporter spoke to a New Zealand plant geneticist who's been working on these onions. Collin Eady, from the Crop and Food Research institute, has found a way to block the gene in the onion cells which cause a person to tear up.
That mechanism is a natural defense for the onion. It's caused by the combination of the tearing gene and natural levels of sulfur in the cells of the bulb. Those components are separate in the whole cell, but its blinding power is unleashed when cut.
It will be a while before you'll see them in your local super market. The genetic modification would have to be proven safe for human consumption first. Or Mr. Eady could try and breed that quality into his onions, but that would take at least ten years anyway. Ah well. Stay tuned for some tips on how to avoid the tears when doing battle against those delicious bulbs.
