I had to look up the recipe, which was in a box written in
my grandfather's hand, God rest his soul.
I have modified the recipe a bit over the years, but here is the basic idea.
Once you get the hang of it feel free to experiment with things that suit
your taste. I also make a version of this with codfish and oysters
instead of meatballs. I vary the sour-sweetness a bit for that, skip
the pork neckbones, and add some butter.
Süße und Saure Suppe
Into a large pot add four quarts of light chicken stock.
Add four stalks of celery. If it is green clean the outside
to remove any bitterness.
Add one pound of cleaned pork neckbones. This will add 'richness.'
You can substitute veal bones if you wish (finicky).
One clove of garlic.
Bring to a boil and simmer for 45 minutes.
Remove the bones and celery. I usually take any meat off the bones
and use it in something else, not in the soup. Sometimes I chop it
up and add it to the meatballs or a meatloaf. Sometimes the dog gets lucky.
Take 1 pound of ground beef or veal and 1 pound ground pork and 8 to 16 oz.
of plain bread crumbs in a large bowl. I grind my own meat but that is
your choice. Add salt and pepper to taste. One tablespoon celery powder
(not seeds!) if you have it. One well diced onion.
Mix well with one or two eggs depending on their size.
If the mix seems heavy add up to 1/2 cup milk to soften the bread crumbs.
Salt and pepper to taste. A sprinkle of garlic powder if you are of that persuasion.
Bring the stock back up to a boil. Make the meatballs and add them to
the stock. Cook them until they float to the top on a slow boil.
Remove them and put them on the side in a bowl.
Add one cup of diced celery, one diced leek, one large potato,
and five or six sliced carrots.
Slice and add one lemon, removing the seeds.
Add one package of cleaned and separated chicken wings.
Bring to a slow boil and simmer for about 45 minutes.
Turn the heat down very low.
Add 2 pints of sour cream. Add 3/4 cup of sugar. Mix lightly
without breaking up the carrots and other things in the soup.
Add some stock to the sour cream container and let it cool off.
Add 1/4 cup flour to the stock in the container and mix it well.
Add this back to the soup to thicken it. A rue can also be used.
Now taste the soup broth and add sugar to suit your taste. Do not overdo
but it should taste slightly sweet. Now if it is not sour enough add
a little white vinegar to bring the sourness into balance with the sweetness.
Add back the meatballs and let it simmer for about fifteen minutes. Don't burn.
Add some chopped scallions for color, and ground pepper. Add salt if you wish.
Serve in a bowl with a crusty bread.
The meatballs tend to absorb the liquid overnight. Add some chicken stock if needed.
