Growing up with German grandparents, my Grandma made a soup that we called, of all things, 'Rotten Potatoes' I have no idea where that name came from other than maybe the German word that went along with kartoffel/potato sounded like 'rotten'.
I remember that Grandma made meatballs, nothing unique there, just ground beef, S&P, onion, celery,,,, and then dropped them into a pot of boiling salted (I guess) water - lots of water, along with cubed potatoes. Whole cloves were added to the water and the soup was whitened, not thickened, with sour cream after the meatballs had cooked and soup was on a low simmer, just warming so as to not break the sour cream.
I remember that we all just loved that soup. I may have to try and recreate a batch. Anyone else ever hear of this soup??
