How long it takes to cook the perfect egg. If you hard-boil it, the yolk goes chalky. Soft-boil it, and the whites stay wobbly. Why? Yolks cook best at 149°F, whites at 185°F. Scientists found a fix: Switch the egg between boiling water (212°F) and tepid water (86°F) every two minutes for 32 minutes. This isn’t a breakfast, it’s a culinary hostage situation.
