At least for me it comes from living in this area. A lot of the Pennsylvania Dutch communities come from German ancestry and along the years pork & sauerkraut (and mashed potatos, with a slab of butter on top... can't forget them!) became a New Years Day tradition meant to bring good luck for the new year.What is it with you guy's and pork and sauerkraut? LOL!
I'm form a German family and we never eat pork and sauerkraut.
How did this become a tradition for you to have on New Years Eve?
