This year, I really want to avoid the last minute flusters.

However, I want everything to be really good.

On the good side, I am only cooking for 4--but of course we have to have
enough leftovers for everyone to take home.

Is there a way to make homemade mashed potatoes ahead of time and have them
be just as good? Or is that the one thing, along with the bread, that I need
to do just before serving? I'm using russets if that matters. Thanks!
