If the knödel is too sticky or not holding together properly, add the additional breadcrumbs a tablespoon at a time until the mixture becomes easy to form into balls shapes.
Taste and if needed, season again with kosher salt and freshly ground pepper to taste.
Ladle 4 Challah knödel into each bowl. Pour the soup evenly over the knödel and noodles between the 4 soup bowls and serve.
