I have finally learned the culinary secret to a hardboiled egg that peels perfect everytime. This has been adult pursuit of mine and I have only just mastered it. I am also stymied by the sheer number of types of eggs now available: caged, free-range, free-run, cage-free and now PASTURE RAISED. You can even purchase Mayo with Cage Free Eggs. Apparently the housing of the hen is the heart of the matter.
