Hi all,

First, this is a great group, got lots of suggestions from last post.
To continue, sometimes when I peel an egg, it has a gray coating
on the yellow inner part. I assume that this is from boiling too
long?
Is there a device that keeps the yoke in the center of the egg
while boiling so that the yoke doesn't settle next to the shell before
hardening?
Is there a special manual manipulation technique for accomplishing
the same result?
Can a microwave ever be used to make boiled eggs? I have
heard of "exploding eggs" so I thought I would ask first.

thanks,
charles.....
