Flavor of Onions and the Cause of Tears

The source of the distinctive flavor and pungency of onions is diallyl sulfide. It has the effect of making your blood flow smoothly and is also the cause of bringing tears to your eyes. To prevent tears, cool onions in a refrigerator for about an hour or use a sharp knife to cut them.
Since this substance is water-soluble, it seeps out of onions if soaked in water for a long time. Avoid soaking onions in water too long.

Storing Onions

Onions are vulnerable to moisture. To keep their taste, place them in a net or stockings and hang in an airy place with no direct sunlight.
If it is difficult, wrap each onion with newspaper and store in a basket or cardboard box. Newspaper absorbs moisture and can protect onions from moisture.
