The basics for eggs: This is how they can be boiled hard or soft. Soft-boiled eggs, i.e.
liquid yolks covered in set egg whites, are usually ready after four and a half minutes. Hard-boiling eggs can be cooked in hot water for up to ten minutes. After about seven minutes of cooking, the egg white is already firm, but the yolk is creamy and soft. Creamy egg yolk rests on a crispy fried egg white cover with a slightly brown crust.
