Ya know, as potatoes are so easy to prepare, why in the hell would ya freeze 'em?
"Toots" will make the fixins, then make the fry/boil/bake potatoes to add to her stuff. She freezes a lot of clam chowder, soup, etc, but never freezes the potatoes themselves. She always adds the potatoes afterwards.
Looks to me like ya gotta be awful lazy to do it any other way.
