perfect egg yolks

“Maybe I have a hangup on soft boiled eggs, but I’m deeply fascinated by how something simple as an egg can be transformed into such a wide range of textures. I’m talking about pure eggs – no other ingredients added. Playing around with temperature and time can result in some very interesting yolk textures – yolks that are neither soft nor hard, but somewhere inbetween.” –Martin Lersch
