I don't know what it is about these potatoes, from the cookbook Second Helpings from Union Square Cafe, that is so good. Roasting them in sea salt in a cast iron skillet just does....something. I love preparing this recipe; it's almost like a ritual! :) Preparation and cooking times are close guesstimates. I hope you enjoy these as much as I do!

Amazingly good! These should be called roasted potatoes because the roasted flavor really shines through. The potato skins are wonderfully flavored. Add the sweetness of the roasted onions and this is a real winner. I may never "bake" potatoes again. This will probably be served at my next dinner party.
