We're not talking about what's inside of an egg, are we?

Yeah, the top is where the air bubble is.

I'm talking about the Egg, as a whole. How you store it, fat side up, defines the top for me. And also that's how I put them in my egg cooker. Cracking the air bubble makes peeling it super easy.

You literally have to restrain them to have your "top" but okay.
