Step 2: Slice Off Onion Bottom

Picture of Slice Off Onion Bottom
Chop off the onion bottom with all the roots still intact.  The more of a bottom you leave on, the better.  Try for 1.5"-2" of attached "meat".

Allow to dry for a few hours to a couple days in a shaded, well-ventilated area to allow for callousing.

Note:  You might only need a few hours for callousing.  If the cut portions are dry to the touch and slightly shriveled, it very well might be calloused enough.

Note:  I'm skipping the dry time for this Instructable.

"Allow to dry for 1-2 days in a shaded, well-ventilated area to allow for callousing."

Can u elaborate on this statement, why should u let it dry and is it necessary?
