This will sound strange but adding water to the eggs makes them fluffy. I mix in an eggshell of water for each egg. I whip the eggs first, then put in the water and whip some more. Doesn't change the mixture, its just less messy.
Now the 'strange' part, adding milk instead of water, makes the eggs watery!
On a cruise, I go to the omelet station and order 2 eggs over medium or 2 scrambled. Sometimes 2 fried hard, all depends on the mood. I understand the eggs on the serving line are real eggs not military chow hall eggs, but I do the fresh cooked anyway.
