Hard-Boiled
When it comes to hard-boiled eggs, there are two types of people: Those who add the eggs to a pot of water and then bring it to a boil, and those who add them after the pot is already boiling. Does either make a difference? Not really. However, it’s important to flash the eggs in cold water after cooking them, because, according to Michelle Dudash, R.D.N, creator of Clean Eating Cooking School, “that’s what prevents the eggs from getting grey.” Everyone seems to agree on that.
One excellent trick to keep in mind when boiling eggs is that the older they are, the easier it is to peel them. “Because they lose water over time, there’s an air gap between the shell and the eggs,” making younger eggs especially difficult to de-shell, explains Dudash.
Of course, if you’re dying for a hard-boiled egg, but just bought a fresh carton, George Weld of the Brooklyn restaurant Egg recommends piercing the shell with a clean thumbtack. Though he doesn’t know if it’s a scientifically proven trick, he finds, “that it makes them easier to peel.”
