Is this normal?!
Actually under good light looks kinda black/blue.
I cooked liver in butter with garlic and onion powder and had pretty much ate all that. Threw scrambled eggs with the yolks mostly raw on the plate and then a hunk of sauerkraut. As I was eating the eggs touching the sauerkraut juices changed colors before my eyes.
I ate most of it but avoided the border of the two foods.
Two questions: What happened? Will I live?
Eggs have iron and your sauerkraut probably has some hydrogen sulfide (that's probably not a good thing, it's toxic). It's simple chemistry from there Fe + S => black iron sulfides.
