Rinse Cut Onions With Water

While cutting onions, intermittently rinse the cut surfaces with water to wash away volatile irritants being generated at the surface.

1 / 1

You can do the cutting interspersed with just a rinse in water because the molecules are being generated at the surface that you generating by doing the cutting. So if occasionally you just rinse those surfaces, then the volatiles go away and they don't bother you as much.
