Carmelized apples & onions are also great combined with sauerkraut!
I always add caraway seeds too... and saute the sauerkraut in real butter, NEVER BOIL!
Excellent over a really good BEEF Hot Dog! w/casings...
Like Sabrette's, Nathans, Hebrew National, etc...
My favorite Hot Dog is still with Cole Slaw & pineapple chunks, and a good mustard!
