Raw egg yolk, if unbroken and still in its membrane, is free of bacterial contaminants from the eggshell and preserves nutrients better than cooked yolk.

“i would probably use a raw egg yolk because a raw egg yolk is not going to touch the shell of an egg the shell of an egg is where the nutri the excuse me the shell of an egg is where the contaminants are clostridial species can flu back or salmonella we don't want babies to get sick but i think i would probably use a raw egg yolk again this is not medical advice do not do this because you don't have to cook the egg yolk preserve the nutrients and if the egg yolk is still in the membrane it's unbroken it should be free of those bacterial contaminants on the outside of the egg shell”

“I don't worry about getting sick from raw egg yolks because they don't touch the outside shell of the egg which is where bacteria would be”
