Why is my egg white blue?
Raw egg white (albumen) is slightly alkaline, so it can change wine’s anthocyanins to their alkaline color, which is a purplish blue. When cooked, egg whites become even more alkaline. That’s why you saw darker blue on the cooked whites than in the raw ones.
Can you cook an egg at 60 degrees?
