I knew milk! I grew up always adding(A SPLASH for each egg, not a whole dang cup) of milk to my eggs, usually when I was making scrambled eggs, I find it makes the eggs less… dense? but im sure it’d work just as well for an omelette, I just don’t tend to have eggs like that lol. I’ve never added cream though, so I don’t know what that’d do to the texture/taste
lol cheese is a solid addition to eggs as well at least! Definitely recommend trying out a bit of milk the next time you have some scrambled eggs or an omelette, cheese can still be added as well just don’t let those boys lead you astray, too much milk and it will literally never leave liquid state (spoken from experience)

I still question how many eggs were used to make an omelette type thing with a WHOLE CUP of milk + some cream?? There ain’t no way that would of worked with just one or two
