Yes, this is a bogus misleading map.
Some seem too tired and boring, but then you wonder why not everything is stuffing or mashed potatoes.
Others seem so radical we’ve never heard of it even, at all. Even some of the “natives”.
I guess our family was (emphasis, WAS) unusual. Yes we had a great turkey and great stuffing, but ours always (all holidays, actually) had sauerkraut and sausage meatballs, and “German noodles” (nothing but egg noodles with sauteed bread crumbs). And corn pudding. My mother did great corn pudding too.
Sounds delicious. I would guess that most families probably cook the traditional turkey, stuffing, mashed potatoes, etc., and then add some family favorites.
