By "chemical eggs" I mean anything other than a real cracked egg.

ex: "Carton Eggs" = a liquid poured from a carton that hopefully contains some real eggs but probably watered down and definitely with added "natural flavors" and other chemicals. Carton eggs make me quiver for some reason. And definitely are not delicious.

ex: What was served in the KLM Crown Lounge in Amsterdam yesterday morning. I simply wanted 1 real fried egg. Instead, they offered a steaming rectangular vessel of solidified 'scrambled' chemical eggs.

ex: McDonalds Egg McMuffin is served with a real egg by default.
McDonalds Bacon Egg and Cheese Biscuit is served with a "Folded Egg" / eggs poured from a carton by default. See the difference in the menu pics?
Ordering hack: You can request any McDonalds breakfast item to be made with a "round egg" substituted for a "folded egg".
That is the simplest, most easily understood way to request a real cracked egg, not a chemical egg.
