What's wrong with my hardboiled eggs???

[Relleoms]

Steaming eggs for 15 minutes is by far the easiest way I’ve found to cook & peel fresh eggs, and perhaps cooking them on their side instead of on end will help distribute the air sack more evenly?

Not sure if I'm posting this in the right place, but here goes...
I've been having trouble boiling/peeling my eggs. I read that really fresh eggs are harder to peel so I chose some of my older ones. Followed all different methods and finally found a method that seemed to help. My problem is related to the air cell. Why are the bottom's of my hardboiled eggs all hollowed out? Is there some way to prevent this? I had a terrific deviled egg recipe that looks ridiculous!

Steam your eggs for 13 minutes and then put them in a bowl of ice water to cool immediately. You will never boil an egg again!
