Ok, Hazan and Bittman say no egg, many others add egg or yolks. To egg or not to egg? Second, should I boil or bake the potatoes? Again, Hazan and Bittman say boil, but others recommend baking so they don't get waterlogged. I'm not one to question the experts, but am tempted to bake. Also, I'd like to make them a few hours before folks get here and then boil and sauce them when folks arrive. Are there any problems with that? Thoughts for a first timer? Help!
