Perfect! If anything, they were actually a little undone. The center of the yolk was not quite as opaque as the rest of the yolk, but I would consider all of your advice excellent since they turned out so well. Oh, and no gray/green at all! I was surprised but since the center wasn't quite completely done, I guess they weren't overcooked at all. Don't know how that could be after 12 minutes.....

I've racked my brains and for the life of me, I can't ever remember exploding anything - what a boring life I've lived.
